JUST LIKE BARTON The set of BARTON stories is an attempt to reach all children, through the creation of a character, who best epitomises the enacted school curriculum. Barton is a curious, well- mannered individual and represents an ideal child who is moulded by all the intended learning experiences of school. The entire curriculum is supposed to transform individuals into a character, just like the boy Barton. JUST LIKE BARTON targets the child at the lower level of the primary school. At this level, the child would have mastered some of the mathematics content expected at the primary level and the problems emphasise the process goals of mathematics, rather than a wide range of content. This set of stories focuses on building model personality characteristics and close relationships with family, friends, and the society. The stories use an approach to learning that not only integrates all areas of the curriculum but merges two essential areas, mathematics and language arts. The emphasis on building literacy skills is deliberate since comprehension is a key area needed for developing an understanding of mathematics. Too often, mathematics has been presented as a set of rules and procedures, to be applied in situations that have no bearing on reality. In these stories, the problems are practical and useful and can serve to whet the child’s appetite into learning the subject outside the constraints of rules and formulae. The stories appeal to the child’s intuitive and imaginative tendencies and encourage the use of strategic and critical thinking, in a context that is meaningful and relevant. These reasoning processes are developed through reading for a purpose - to solve a problem. It is hoped that through these stories, students will learn not just to be creative and critical problem solvers, but to acquire good habits and become caring and productive citizens. The stories are laden with sound moral, social and ethical values and teachers may take the opportunity to encourage discussion on the consequences of certain actions, or what other Copyright ©2021.Some Rights Reserved. faspassmaths.com 4
alternatives are possible. They may also use the stories as stimulus material that can be further reinforced in other areas of the curriculum. For the more mature student, small group work is recommended whereby discussion is limited to a few students and this can be followed by sharing of ideas from each group, in whole-class settings. Fayad W. Ali & Shereen A. Khan GUIDE FOR TEACHERS The book ‘Just like Barton’ was written with the intention of enriching the primary school curriculum. Teachers can use the book in the following ways: 1. To motivate students to read. When students read stories in which they have to extract information and extend their imagination, they read with a purpose. The visuals are also provided to entertain, to offer vocabulary clues, and to appeal to several of the child’s senses. 2. To develop skills in vocabulary, word study, phonics, and spelling. Students will encounter new and challenging words as they read the stories and teachers can use this opportunity to teach phonetic sounds and build vocabulary. 3. To teach comprehension skills in mathematics and language arts. Teachers can create questions about each story, to test students’ comprehension skills. These questions can be based on the mathematics covered or basic understanding of the story. The following are suggested activities for developing comprehension skills. Copyright ©2021.Some Rights Reserved. faspassmaths.com 5

To present mathematics using authentic situations Children will have the opportunity to experience mathematics as a tool to solve problems. Teachers can now preview the stories for a particular topic or cluster of topics. Next, ensure that pupils have the necessary previous knowledge by constructing practice exercises to review the content needed. The stories provide opportunities to enrich student understanding of the content through experiences that they encounter in real life. As students begin to read the story, allow sufficient time for problem-solving through group work and student demonstrations. 5. To allow for the integration of subjects with mathematics in the primary school curriculum. Copyright ©2021.Some Rights Reserved. faspassmaths.com 6
There are numerous opportunities for incorporating the various curriculum areas. For example, teachers can allow students to draw or dramatise situations to demonstrate their own interpretations of the plot, thus incorporating the Visual and Performing Arts. Some stories have a subject-specific focus incorporating curriculum areas such as Character Education, Morals, Values, and Family Education. These can be used as introductory lessons in a unit. Other stories may centre around a particular theme and provide opportunities for incorporating different models of integration in the curriculum. 6. Provide stimulus material for teaching values through situations that are realistic, age-appropriate and easy to enact. The stories can be used to generate class discussions and so provide opportunities for value clarification without the teacher having to impose personal values. Some of the stories are strong on a particular set of core values, and the teacher may select a story to match a particular theme or topic that is relevant to student needs. Fayad W. Ali & Shereen A.

BARTON ON A MORNING Barton A. Sandiford awoke promptly upon hearing the sound of his alarm clock. The young boy glanced at his analogue clock, which showed the time as a quarter past six. Then, he looked at his digital alarm clock, which boldly displayed the time as 6: 15 a.m. Barton did not delay but hurried off to brush his teeth and to shower. In his hand, he held a tube of toothpaste. A filled tube contained one hundred and fifty millilitres of toothpaste and this amount would usually be used by Barton over a period of thirty days. Therefore, on average, Barton would use five millilitres of toothpaste per day. Including today, Barton had used the tube of toothpaste for a total of six days. It was expected that the tube would still have about 120 millilitres left. Barton calculated that the remaining amount might last him for another twenty-four days and which is three weeks and three days when converted into weeks and days.

Barton was fully dressed and ready for breakfast twenty minutes after he awoke. He fastened his watch around his wrist and which now showed the time to be 6:35 a.m. The well-rested and smiling boy greeted his mother and his two siblings as they all sat down to breakfast. Dad had already left for work. He usually departed one-half of an hour before Barton awakened. This was at the rather early time of 5:45 a.m. Mom and Dad would set their alarm clock to awaken one hour before Barton did. This was at a time of 5:15 a.m. Barton had one brother and one sister, and so the family comprised of five members in all. His brother, Darren was nine years old, and two years younger than Barton who was eleven. The sister, Cathy- Ann, was one-half of the total age of Barton and his brother. She was ten years old. Barton had calculated that the combined age of all three children was thirty years. Their names, starting from the youngest to the oldest were Darren, Cathy-Ann, and Barton. Mom was three times Barton’s age and was thirty-three years old. Dad’s age exceeded Mom’s age by two years, and so he was thirty- five years old. Dad would often have his breakfast at work. That time was much earlier than when the rest of the family did. The rest of the family members usually had cereal, sausages, toast, cheese and eggs for breakfast. Copyright ©2021.Some Rights Reserved. faspassmaths.com 10
Each one of them, except Dad, used one small box of cereal per morning and Mom bought them in packs holding twenty-four such boxes. She would buy two of these packs at a time and they lasted for twelve days. For breakfast, Barton would eat two eggs, the same amount as Mom. Both Darren and Cathy-Ann would have one each. The number of eggs used each morning by the family was six. Eggs were bought in crates containing thirty each. Mother bought three crates at a time and the total was enough to last for fifteen mornings. From a filled carton, with a capacity of one and one-half litres, and which was 1 500 millilitres, Barton would pour each member of the family a glass of orange juice. Each glass held one hundred and fifty millilitres. The total amount of orange juice poured, in millilitres, was 600 and the amount that remained was 900 millilitres. The remainder was enough to fill six glasses. Copyright ©2021.Some Rights Reserved. faspassmaths.com 11
After breakfast, Cathy-Ann often chose to help Mom with the dishes. Each of the diners would have used one each of a plate, knife, fork, spoon, saucer, bowl and glass. The total number of utensils used by the family at breakfast was twenty-eight. Together with a saucepan, two pots and a large cooking spoon, the total number of items that needed to be washed on mornings was thirty-two. It would take Mom or Cathy-Ann an average of half a minute for each utensil and so the expected time to complete the washing of dishes was about sixteen minutes. Barton would then proceed to complete his morning chores. He would make his bed, taking about five minutes to do so. Then he would empty the garbage which took a further four minutes. Copyright ©2021.Some Rights Reserved. faspassmaths.com 12
His final job was to feed and tend to the dog, which took up to six minutes. His younger brother’s chore was to rake the fallen leaves from the lawn and which took him approximately twelve minutes to complete. The child, who finished first, usually brought in the newspaper. There was always some excitement among the children in doing their morning chores, as they competed to be the one to bring in the newspaper. On most mornings, the newspaper was brought in by Darren. Then, after kissing Mom good-bye the three happy children headed off to their school and which was not too far off. Copyright ©2021.Some Rights Reserved. faspassmaths.com 13
BARTON AT THE SUPERMARKET It was a bright and sunny Saturday morning as Barton listened to the chirping of the birds outside his home. Barton readied himself as he was going to accompany Mom on a small trip. The time was exactly half-past eight when Mom and Barton drove off to the supermarket in the family car. Barton always liked the licence number of their car, as it read, 1 3 5 7. It was easy for him to remember these numbers as the digits are the first four odd numbers. Interestingly, all of them, except the digit 1, are prime numbers. Barton often thought that if the digit, one, was changed to two, then all four numbers on the licence, would not only be different digits and in ascending order, but also the changed digit, two, would be special, as it has the distinct and unique property of being both even as well as prime. On the way, Mom noticed that the gas meter on the car read one- quarter full or three-quarters empty and so she decided to fill the tank at the nearby service station. The capacity of the car’s gas tank was eighty litres and it, therefore, needed sixty more litres of gas to be filled. Copyright ©2021.Some Rights Reserved. faspassmaths.com 14
The price of the fuel was $ 3. 50 per litre and the total cost to fill the tank would be $ 3.50 x 60 = $210. Mom paid with $300 and the correct change of $90 was given to her in five currency notes, made up of four $20 bills and one $10 bill. Both mother and son arrived at the supermarket at 8:45 a.m., exactly one-quarter of an hour after leaving home. Copyright ©2021.Some Rights Reserved. faspassmaths.com 15
Barton felt quite excited. He loved walking through the various aisles, looking for items that were on sale, to show Mom. He also liked to observe the new products which appeared on the shelves and he would read their labels with the written information on the contents. The young boy thought of himself as a good shopper, especially as Mom often complimented him on the fine choices he would make when they shopped together. Barton happily pushed the shopping cart along and was quite anxious to show Mom his literacy and mathematical skills. It was not too long before his keen eyes saw the first bargain. One of his favourite foods, sausages, was being sold at $2.00 per can. However, a pack containing six cans would cost $10.50. Barton quickly calculated the sales price to be $1.75 per can. Copyright ©2021.Some Rights Reserved. faspassmaths.com 16
This would be 25 cents less per can than if the cans were bought singly. Mom decided to buy two of these packs of sausages and Barton easily calculated the overall savings to be $3.00. In another aisle, they saw potatoes pre-weighed in bags of either two kilograms or three kilograms. Mom wanted exactly ten kilograms, but she preferred this choice to be with the least number of bags. Barton again did a quick calculation and decided correctly on two of the 2-kilogram bags and two of the 3-kilogram bags. Flour was next on their shopping list and was sold in smaller packs weighing two kilograms at $6 per pack. They were also available in larger packs weighing twelve kilograms each and sold for $36 per pack. Mom wanted twelve kilograms of flour. Barton decided to work out the unit price of the flour, that is, the price per kilogram. He wanted to know which of the two packs would have the flour sold at a lesser cost per kilogram. In the end, the two shoppers realised that either buying six of the 2-kilogram packs or the single bag of 12 kilograms, would cost the same. As the two shoppers moved along the aisles of the large supermarket, Mom realised that she had forgotten to purchase seasoning powder. Barton rushed across to the aisle where the item was sold. The powder was to be found on a shelf situated in the last aisle. They were available in packs of 25 grams each. Mom asked Barton to fetch a total of one-quarter kilogram of a special brand of the seasoning powder. Copyright ©2021.Some Rights Reserved. faspassmaths.com 17
Barton would have to calculate the number of packs that would be required. He found this number to be ten and so Barton counted out ten packs. After purchasing a few more items, Mom and Barton headed towards the cashier. Barton wished to see if he could calculate the bill faster than the girl at the cash register. The young mathematician quickly pulled out his notebook and pencil and listed the prices of the items. Item Cost 2 packs sausages at $10.50 per pack $21.00 10 kg potatoes at $1.25 per kilogram $12.50 1 pack 12 kg flour at $36.00 per pack $36.00 10 packs seasoning at $3.50 per pack $35.00 2½ kg fish at $36.40 per Kg $91.00 5 packs of rice at $2.80 per pack $14.00 1 chicken weighing 2 kg 800g at $6.00 per kg $16.80 1 chicken weighing 2 kg 700g at $6.00 per kg $16.20 Subtotal $242.50 10% discount with ‘Shoppers-D-Lite’ card $ 24.25 Total amount $218.25 The total cost was $218.25. From the $300.00 that she handed to the cashier, Mom received the change of $81.75. She gave a tip of $5 to the helpful girl who rolled the cart of groceries to the car. Copyright ©2021.Some Rights Reserved. faspassmaths.com 18
As they drove homewards, young Barton calculated that the overall cost at the grocery store alone was $223.25. Barton further calculated that for the entire morning, Mom had spent a total of $433.25 before their return home. Copyright ©2021.Some Rights Reserved. faspassmaths.com 19
BARTON IN TRAINING There was much excitement with the announcement of the date of the school’s Annual Sports Day. Barton immediately decided to begin a period of physical training. He was a good athlete and wanted to be fitter and more ready than he was at the present so that he could perform at his best. He usually took part in several events and was able to manage his time for studies, leisure and sporting activities quite competently. Sports Day was three weeks and four days away and Barton planned to train on each of the twenty-five days, before the day of the gala event. The young sportsman decided that he will exercise each morning before he went to school. He set his alarm clock to ring at 5:55 a.m, twenty minutes before his usual awakening time, which was at a quarter past six. Barton’s exercise routine started with three minutes of stretching and four and a half minutes of push-ups. The total time spent on these two exercises was now spent on abdominal exercises. This entire exercise routine took a total of fifteen minutes. The lunch break at school was from 11.20 am to 12.30 pm, which was for one hour and ten minutes. It provided enough time for Barton to jog around the school ground. The ground was circular in shape, and with a diameter of one hundred and twenty-six metres. It, therefore, had a radius of sixty- three metres. The circumference was three hundred and ninety-six metres and Barton would jog around it twice. Copyright ©2021.Some Rights Reserved. faspassmaths.com 20
This was a total distance of seven hundred and ninety-two metres. Barton usually completed the entire distance in a total time of six minutes and thirty-six seconds. His average speed was two metres per second. He hoped to increase his speed by one-half of a metre per second so that his new average speed will be two and one-half metres per second. After the lunchtime jogging, Barton would take a quick shower at the school gymnasium and return refreshed for the afternoon session of school. This period of class-time would last for two hours and ten minutes. Then, the school would be dismissed at 2:40 in the afternoon. After arriving at home, Barton would settle down and help Mom with a few minor household chores. Then, he would begin his homework promptly at four o’clock. Copyright ©2021.Some Rights Reserved. faspassmaths.com 21
The disciplined student would work uninterrupted, taking between one hour and a half and one hour and three-quarters to complete. He would finish between 5:30 p.m. and 5:45 p.m. The hard-working Barton would never rush his homework, and on the days when more time was required, he would continue without complaint until he felt that it had been done satisfactorily. Because of his training routine, Barton would resume his training for Sports Day with some weight lifting at 6 p.m. He used a bar weighing two kilograms and would add equal weights at the ends. This ensured a proper balance. Barton would lift a total of eight kilograms as the weights at each end weighed three kilograms. Sometimes, Barton would attach a further one kilogram on each side for a total weight of ten kilograms. Barton would lift the bar with weights, at an average rate of four times a minute and would continue this routine for one-quarter of an hour. In the end, he would have lifted the bar with the attached weights, a total of sixty times. After a shower and dinner, Barton, together with the rest of the family, would listen to both the local and international news. Later, he and his siblings may watch a movie or play a game, sometimes with Mom and Dad participating. Barton tried to always get eight hours of sleep each night and therefore headed off to bed for the latest at 9:55 p.m. so that he can rise at the sound of his alarm. His schedule was now slightly different from the norm, as he was in training for his school sports day. Copyright ©2021.Some Rights Reserved. faspassmaths.com 22
BARTON AT THE TYRE SHOP It was the month of June, the sixth month of the year, and the weather had begun to change from sunny to rainy. During the rainy season, the roads would become frequently wet and slippery and drivers always needed to exercise extra caution whilst they drove, to avoid causing accidents. Having a vehicle equipped with good tyres, ones that were not too worn, was also a necessary safety requirement. Mr Sandiford decided to change the tyres of the car since they were already half worn. He invited Barton to accompany him on this venture. So, at 8 o’clock that Saturday morning, Dad and son headed off to the nearby tyre shop. Copyright ©2021.Some Rights Reserved. faspassmaths.com 23
The shop was only five kilometres away and they drove for only ten minutes. The car was driven at an average speed of thirty kilometres per hour and the two arrived at BEST RIDE TYRES at ten minutes after 8 o’clock. There were two vans, one truck, three cars, and two SUV’s ahead of them, so they were parked ninth in line. Barton and Dad did not alight from the vehicle but remained in line and seated in their vehicle. Fifteen minutes after arrival, at 8:25 a.m., one of the friendly attendants was ready to work on Mr Sandiford’s car as the vehicle had now progressed to be first in line. Dad chose tyres which were priced at $250 each. However, if he were to purchase a set of four tyres, he would receive a 5% discount. The attendant advised Mr Sandiford that it would be wise to also change the four valve stems as well and also to add the required amount of weights on each tyre rim for proper balancing. The helpful attendant went on to explain that ‘balanced tyres’ would not only help to provide a smoother riding vehicle but would also greatly increase the lifespan of the tyre. Dad listened attentively and accepted all the advice given to him by the knowledgeable attendant. The job was carried out without any problems and the four new tyres were fitted onto the Sandiford’s family car. The bill was prepared by the attendant and Barton requested to look at it. The young boy was quite adept at arithmetic and was always looking for an opportunity to demonstrate his skills in the discipline. Copyright ©2021.Some Rights Reserved. faspassmaths.com 24
Barton proceeded to check the costs and to calculate the total amount due. He used his pencil and notebook, both of which he usually kept in his pocket. RECEIPT ITEM COST 4 tyres priced at $250 each $1 000.00 Discount of 5% $50.00 NET COST OF ALL THE TYRES = $1000 − $50.00 $950.00 Cost of 4 valve stems at $6 each $24.00 Cost of 6 g weights at $4 per g $24.00 Labour cost $60.00 TOTAL before VAT $1 058.00 Value Added Tax of 15% $158.70 TOTAL COST $1 216.70 Dad gave the attendant a ten dollar tip. Dad was most grateful to him for his professional work and more so for his kindly advice. The attendant was quite thankful. Copyright ©2021.Some Rights Reserved. faspassmaths.com 25
At a soda machine situated inside the shop, Dad inserted a $5 bill and three $1 bills to purchase two sodas for Barton and himself. The sodas cost $4.00 each. Barton performed another calculation to realise that the entire morning’s expenses came to a total of $1234.70 thus far. As Barton and Dad journeyed back home, Dad saw a group of college students accompanied by their teachers, offering to wash cars to raise funds for a local charity. Dad observed some of the vehicles which they had completed and was pleased with the result. The students charged twenty dollars for a car wash. Dad decided to support the worthy cause and at the same time, get the benefit of a clean car. The students were most happy to oblige. Copyright ©2021.Some Rights Reserved. faspassmaths.com 26
As the group of enterprising students washed the car, Barton and Dad decided to go to a nearby store to purchase a pair of slippers for his sister, Cathy-Ann. The regular cost of the slippers was $30 per pair. On that morning, however, the store had a special offer. With the purchase of one pair of slippers, another pair can be bought at half the price of the first pair. If customers purchased a third pair, they would pay one-third the price of the first pair. Dad thought this was indeed a good bargain and decided to buy five pairs for all the members of the family. He asked Barton to calculate the cost of the five pairs based upon the offer. Barton used his knowledge of arithmetic and wrote, The cost of the first pair = $30. The cost of a second pair = $15 The cost of a third pair = $10 The cost of the fourth pair = $30 The cost of a fifth pair = $15 The cost for the five pairs of slippers, based upon the offer, = $100 Dad was pleased with the figure but noted Barton had not realised that a value-added tax of 15 % should be added to the total price of the five pairs of slippers. This was quickly calculated to be $15. The total cost of the five pairs of slippers was now found to be $115. After purchasing the five pairs of slippers, Dad paid the students for the car wash and the two drove off in the clean and shining car. The two headed off for home after a happy morning together. Copyright ©2021.Some Rights Reserved. faspassmaths.com 27
Dad liked to record all the family expenditures and asked Barton to total the expenses for that morning. Barton did some simple addition and found the total amount that was spent that morning was $1 369.70. Copyright ©2021.Some Rights Reserved. faspassmaths.com 28
BARTON’S GARDEN Barton was regarded by all to be a good student. He was kind to his friends and courteous to his all teachers. He was well-loved by his schoolmates and the staff at his school. His schoolwork was usually well done and he was both helpful to others and an attentive student in the class. Miss had recently introduced the weekly lesson on Agricultural Science to her class and Barton became particularly interested in her suggestion of starting a home garden. Mom and Dad also thought it was quite a good idea, and both Barton’s younger brother and sister offered to help with the project. The next evening, Barton walked to the back of their house and with a measuring tape in hand, decided to mark off three rectangular beds. Each measured two metres wide and three metres long. The area of each bed was six square metres and the total area of all three beds was eighteen square metres. Barton decided to erect a short fence around each of the beds. Based on his knowledge of finding the perimeter of a rectangle, he calculated that he would require a total length of thirty metres of fencing for all three beds. With help from his brother and sister and using a few garden tools, the three children prepared the three beds and readied them for planting. Barton had read the notes on Agricultural Science which he had written in class and he followed them carefully. “According to Miss,” Barton told his siblings, “a project of this type can help the community in many ways, one of which is yielding a monetary profit to the planter.” Copyright ©2021.Some Rights Reserved. faspassmaths.com 29
Barton decided that he will keep a record of the cost of everything which he purchased for the project. This would be his expenditure record. He also decided to use money from his savings to finance the project. In the first garden bed, Barton decided to plant spinach. There would be six rows and each row would hold ten plants. This would be a total of sixty plants. In the second garden bed, Barton chose to plant tomatoes. There would be four rows and each row would hold eight plants. This would be a total of thirty-two plants. In the third garden bed, Barton opted to plant lettuce. There would be two more rows than the first bed and each row will have four more plants than the first bed. The third bed will have eight rows with fourteen plants per row, and therefore a total of one hundred and twelve plants in all. With all the beds properly prepared for planting, the young gardener visited the plant shop and showed the attendant the list of the number of plants that he needed. LIST Number of spinach plants = 60 Number of tomato plants = 32 Number of lettuce plants = 112 Total Number of plants = 204 Copyright ©2021.Some Rights Reserved. faspassmaths.com 30
The total number of plants was 204. The bill showed: BILL 1 ITEM COST 60 spinach plants at 20¢ each $12.00 32 tomato plants at 40¢ each $12.80 112 lettuce plants at 15¢ each $16.80 TOTAL $41.60 The helpful and knowledgeable attendant at the plant shop told Barton that in about two weeks after planting, he should supplement the growth of the plants with a small amount of fertiliser. Barton was advised to also spray the young plants with an insecticide for protection against harmful insects. Young Barton was thankful for the advice and agreed to purchase these supplies. At the same time, he would purchase the fencing material from the shop. The second bill showed: Copyright ©2021.Some Rights Reserved. faspassmaths.com 31
BILL 2 ITEM COST 2 kg of fertilizer at $6.75 per kg $13.50 1 can of insecticide -spray at $20.80 $20.80 30 metres of fencing at $1.50 per $45.00 metre TOTAL $79.30 The total cost of all the supplies at the plant shop was $120.90. Barton paid for the items with $200 and received $79.10 change. The young gardener set off for home, anxious to begin planting with the help of his brother and sister. The three children started that evening at 4.10 pm and finished one and one-quarter hours later at 5:25 p.m. All three were tired but happy with the start of their garden. They went off to shower and later to have dinner with their parents. As the days turned into weeks, the three children became very excited as they saw the plants begin to grow and blossom. They took great care in watering, fertilising, spraying and in the removal of the weeds that cropped up from time to time. Copyright ©2021.Some Rights Reserved. faspassmaths.com 32
It was an enjoyable feeling and the children marvelled as they looked on with pride at their little garden. They were able to experience, ‘first hand’, the great miracle of growth. Between the eighth week and the tenth week, the spinach and the lettuce were all ready to be reaped and the tomato trees were laden with red ripe produce. It was a beautiful sight to behold and both Mom and Dad would sometimes look on and encourage the three children. Mr Albernatty was one of Dad’s close friends. He was a vegetable vendor and on one of his visits to the Sandiford home, the old man looked at the beautiful little garden. Mr Albernatty was quite pleased to see the great work of the children. He made an offer to purchase all the vegetables from Barton’s garden and Barton readily agreed. Dad and Mom decided to leave Barton and Mr Albernatty to their own discussion concerning the prices at which the vegetables would be sold. Copyright ©2021.Some Rights Reserved. faspassmaths.com 33
Mr Albernatty offered Barton $4 per head for each of the 112 heads of lettuce, as he planned to sell them at $6 per head. The old man would hope to make a profit of $2.00 per head and a total profit of $224 if all of the lettuce were sold. Next, Mr Albernatty offered Barton $8 per head for the spinach, as he planned to sell them for $12 per head. In the purchase, he would hope to make a profit of $4.00 per head and an overall profit of $240 if all of the 60 heads of spinach were sold. Finally, he offered to buy the tomatoes at $10 per kilogram and he would sell them at $15 per kilogram. Barton’s tomato crop yielded a total of 40 kilograms. Mr Albernatty hoped to make a profit of $200 on the sales of the tomatoes. Copyright ©2021.Some Rights Reserved. faspassmaths.com 34
He listed the total sale value to Barton, which read: TOTAL SALES 112 heads of lettuce at $4.00 each = $448.00 60 heads of spinach at $8.00 each = $480.00 40 kg tomatoes at $10 per kilogram = $400.00 Total = $1328.00 The total amount that Mr Albernatty was prepared to pay was $1328. Barton considered the offer to be quite handsome and agreed readily to the proposal. Barton, together with his brother, sister, and Mr Albernaty, reaped the products from the garden. The old man loaded the fine, fresh produce onto the tray of his truck. He paid the agreed price to Barton before leaving with the vegetables. Mr Albernatty’s total profits when he sells all the vegetables should be $664. Barton was quite anxious to check his profit after Mr Albernatty left. He remembered his previous output of money and which he had carefully noted. Barton sat down and calculated: Total received from the sales of vegetables was $1 328. Total expenses for plants, fertiliser, insect spray and fencing was $120.90 Copyright ©2021.Some Rights Reserved. faspassmaths.com 35
Overall profit = ($1 328) – ($120.90) = $1 207.10 Barton decided to keep half of the profits for himself, and because his brother and sister had helped him, he would share the other half equally between the two of them. He would then receive $603.55 and his brother and sister should receive $301.77 each. There’s an extra cent laughed Barton when the decision was made, so I’ll give $301.78 to our one sister. The two brothers laughed and Cathy-Ann blushed. How right Miss was when she taught the lesson, Barton thought. Barton decided that he will tell Miss, and perhaps even the class, about his wonderful agricultural project and his success as a gardener. I wonder what my next three crops will be, thought Barton, as he placed the small wad of bills in his savings box. Copyright ©2021.Some Rights Reserved. faspassmaths.com 36
BARTON AT THE BEACH It was a beautiful Saturday morning that greeted the Sandiford family as they awakened. Barton was roused by the chirping of birds outside his window, even before his alarm clock chimed. Each night, Barton would place fruit and bird seeds in a dish on the window sill for the birds to eat in the morning. He purchased the seeds in small packets which cost $15.00 each. Each packet held 300 grams and the content was evenly divided over a period of days. On average, this was about thirty grams per day and the cost of bird seeds, per gram, was five cents. About twenty birds enjoyed the free breakfast every morning. On this particular day, the Sandiford family had planned to go to the beach. So, after a quick breakfast and a change into beachwear, the excited family huddled in the car and headed off to spend a relaxing day in the blue waters and on the golden sands of their favourite beach. They left home at 9.10 am and the beach was thirty kilometres away. Copyright ©2021.Some Rights Reserved. faspassmaths.com 37
As Dad drove at an average speed of forty-five kilometres per hour, the expected time for the trip was forty minutes and the time of arrival would be around 9:50 a.m. or ten minutes to 10 o’clock. Barton, his brother Darren, and sister, Cathy-Ann, often played a special game on long trips. They would check one hundred vehicles that drove by in the opposite direction to which they were moving. They would note the first number of the number plates of the vehicles. One of the three would choose even numbers, the other would choose odd numbers and the third would record and tally the scores. The number of odd or even numbers, whichever was the greater, identified the winner. On this morning, Barton was given the first choice and opted for even numbers. His brother, Darren was therefore not given a choice and remained with the option of having to take the odd numbers. Barton’s numbers would be 2, 4, 6, and 8 and his brother’s numbers would be 1, 3, 5, 7, and 9. Since the number of even numbers from 1 to 9 is one less than the number of odd numbers, the player who chose or was given the pick of odd numbers would be asked to omit one of these numbers from the scores. This was because the person who chose or was given the pick of odd numbers would have had a greater chance of winning if this was not done. This, of course, would be unfair. The number to be omitted would be decided upon before the game started. Copyright ©2021.Some Rights Reserved. faspassmaths.com 38
On this day, the number nine was omitted by Darren and Cathy-Ann opted to score. The boys kept a keen lookout for the first number of the license’s plates of the oncoming vehicles whilst Cathy-Ann kept score. As some of the vehicles passed by in quick succession, the recording was sometimes difficult. Cathy-Ann, however, successfully transferred all the recorded scores onto the final tally sheet before she handed her two brothers the table of scores. NUMBER TALLY TOTAL 1 |||| || 7 2 |||| |||| || 12 3 |||| |||| |||| 18 ||| 4 |||| | 6 5 |||| |||| |||| 14 6 |||| ||| 8 7 |||| |||| |||| 14 8 |||| |||| |||| 21 |||| | TOTAL 100 Together, all three checked the score sheet for any discrepancies and proceeded to determine the winner. Copyright ©2021.Some Rights Reserved. faspassmaths.com 39
They discovered the modal score turned out to be eight. The total number of odd numbers occurring was fifty-three. The total number of even numbers occurring was forty-seven. At the end of completing the sheet, it was discovered that the winner of the game was Darren. When the odd numbers were counted, Barton showed another way to find the number of even numbers which was beside counting the tally marks. This was because the number of odd numbers that was noted, subtracted from the total of 100 scores would be the number of even scores. The winner basked in the glory of victory as the journey continued. It was not too long after the game was completed, that the wonderful scent of sea-breeze filled the air. Dad reduced the speed of the car for a short while, allowing the family to enjoy the beautiful sight of a grove of swaying coconut trees, laden with fruit and glistening in the blissful morning sun.

Shortly after, blue coastal waters sparkled in front of them. They could hear the rising, crashing, and ebbing of the waves roaring as they spewed edges of white foam upon the shore. It was the start of a fun-filled day at the beach for the Sandiford family. The family thoroughly enjoyed bathing and swimming and playing games. Barton saw a few small, live clams on the sand. He dug into the sand with his bare hands and came up with a handful of the creatures, locked in their beautiful shells. Barton decided to dig for more and collect them in bags. Mom would make a fine dish with them. The family joined him and they filled five small bags with about two hundred each, a total of about one thousand. Mom said each bag will yield about fifty grams of clam meat. They expected about two hundred and fifty grams or one-quarter of a kilogram of meat in total. There continued to be so many exciting things to do and to see at the beach as the day passed by. Barton had been observing a small boat sailing from the deeper waters towards the shore. As it landed on the shore it appeared to be about one-fifth of a kilometre or two hundred metres away from where the Sandifords were. It was a fishing boat and Barton and Dad decided to have a look at the fishermen’s catch. The two took a jog towards the boat. Copyright ©2021.Some Rights Reserved. faspassmaths.com 41
As they got closer, the two could see baskets of freshly caught fish and shrimps in the boat. Dad and Barton noticed a nearby vendor and her assistant waiting on the shore, likely ready to purchase the entire catch. There were three baskets of shrimps, each holding 10 kilograms. At the price of $40 per kilogram, a total of one thousand and two hundred dollars was expected in sales. There were also two large baskets of fish, each holding 30 kilograms. At $10 per kilogram, a total of six hundred dollars was expected in this separate sale. An old and friendly fisherman, who was both the owner and the captain of the boat, had been observing the keen and curious Barton. He immediately liked the young, bright-eyed boy and decided to offer him a fine fish if he could answer a question. Copyright ©2021.Some Rights Reserved. faspassmaths.com 42
The fisherman beckoned to Barton and showed him a fish that he had kept in the boat. He explained to the young boy that he would give to him the fish, if he could guess its weight, to within a quarter of a kilogram. Barton knew that this meant he must choose a weight which is to be no more than one-quarter of a kilogram in excess or one-quarter of a kilogram less than the correct weight of the fish. Barton recalled going to the market with Mom not too long ago and she had purchased a fish, weighing 2 kilograms. The one shown to him by the old fisherman seemed to be similar in shape and just about three times the size. A quick multiplication and Barton decided to choose the weight of three times the weight of the fish which Mom had bought at the market. He chose the weight of six kilograms. The fisherman laughed as he weighed the fish and found the scale reading to be 5kg 850g. The difference between Barton’s answer and the actual weight was one hundred and fifty grams. Barton A. Sandiford was presented the fine fish amidst applause from all those around. The late evening approached. The Sandiford family had spent a long, wonderful, and exciting day at the beach. They enjoyed the food and drink and most of all having fun in the water and on the sandy shores. As they drove home, tired, and a bit sunburnt, they agreed that it was a most enjoyable day and they all looked forward to the next family outing. “Mom,” said a happy Barton, “can I make a suggestion for dinner tomorrow?” Copyright ©2021.Some Rights Reserved. faspassmaths.com 43
BARTON’S POEM One morning at school, after Mathematics class was over, Miss announced that there was going to be a poetry competition. The special event was organised to commemorate ‘World Mathematics Day’. The competition was open to the entire school population and the title of the poem was, ‘Why I love Mathematics’. Large and colourful posters advertising the competition were stuck on the walls all around the school. They were expected to raise awareness of this important day and also of the competition. Miss, was certain that her students knew the importance of mathematics and its relation and applications in everyday life. She expected several of her students to enter the competition and was very anxious to read the poems that they might compose on the subject. Barton was quite excited to compete and devoted a few evenings to prepare and complete his entry for the competition. This was Barton’s poem. Copyright ©2021.Some Rights Reserved. faspassmaths.com 44
WHY I LOVE MATHEMATICS I love my maths so very much I see it every day In all I hear and do and touch In class and when I play I need to count and multiply Divide and subtract too And maths is always there to try In everything I do All things above or on the ground Have volume, height, and weight With perimeter all around Charts, areas, time and date Our world is surely not without Modern technology So filled with maths, no one can doubt Its great necessity Now we can so clearly see This Empress rules the World So master Maths and we will be With gifts worth more than gold. By Barton A. Sandiford Copyright ©2021.Some Rights Reserved. faspassmaths.com 45
Barton recited his poem for the students of his class. They were all quite proud of his creativity and style. His classmates thoroughly enjoyed it and applauded him. Miss too, was quite impressed and she patted him on his shoulder, smiling happily. Maybe one day I shall publish a book on Barton’s poems, thought Barton, as he walked back to his seat. It shall be named ‘Barton’s Anthology’. Copyright ©2021.Some Rights Reserved. faspassmaths.com 46
BARTON ON NUMBERS On “World Mathematics Day”, Miss decided to talk to her class about the significance of the date, March 14th, and what it meant in the mathematical world. She explained to her students that ‘World Mathematics Day’ commemorates the origin of the important symbol π and which is the Greek letter, pi. She told her amazed class that pi represents a mathematical constant that has a value of 3.14. This, however, is an approximate value, when written correctly to two decimal places. As an improper fraction, the value of pi is !! approximated to the fraction, . " Miss then added, with a tone of mystery in her voice, that they will probably learn, in the future, just how the figure of 3.14 was derived and why its value is constant and can never be altered. Each year, Pi day is celebrated on the 14th day of March. “Look at the digits in the number 3.14,” said Miss. “Notice that the first digit is 3 and March is the third month of the year. The next two digits are 1 and 4 and so the day is chosen as the 14th day of the month.” Miss spoke to her class about the importance of numbers in mathematics and everyday life. The students were all engrossed in her lecture. As Miss ended her talk, she suggested that her students write a short story or poem on what numbers meant to them. Copyright ©2021.Some Rights Reserved. faspassmaths.com 47
All were excited to do so and Miss always admired their creative skills, whether it was in reading, creative writing or in the visual and performing arts. Barton thought about what he might do. At first, he thought of writing an essay based on some research on ‘pi’. However, he felt that this would be a common choice among pupils and Barton wanted to do something that was different from most of the other students. So, instead, the young boy opted to write a poem. Though quite young, Baton was an avid reader and was already acquiring good literary skills. This is what Barton wrote. NUMBERS Since ancient times, history has shown Numbers, man did create And today, though maths has grown Numbers, still fascinate Divide by two, remainder none And EVEN is its name But when we have remainder one The ODD one takes the blame All fractions have a vital role Sometimes alone they stand They can cut or split a whole Like rivers through the land Whichever form they may appear Improper, part or whole Just look and touch you’ll feel and hear How numbers shape our World.

BARTON’S NEW STUDY ROOM It was the month of March and the third month of the year. On one of the evenings, after dinner, Mr and Mrs Sandiford held a family discussion. They both expressed much satisfaction with the three children. The proud parents were pleased with their children’s behaviour, attitude and especially their outstanding performances at school. Mom and Dad had recently attended the school's ‘Annual Parents Day’. The teachers all had wonderful things to say about Barton, his brother Darren, and his sister Cathy-Ann. They commended the children’s superlative performances in school concerning classroom work, partaking in class discussions, participating in class and school events, school attendance, overall discipline and their willingness to help others. Both Mom and Dad understandably felt a deep sense of pride and contentment with all of their offspring. Meanwhile, Mom and Dad had been noticing that when the three children were engaged in studies at home, they would often participate in discussions with each other. They would sometimes need to give or get advice from each other, explain the meaning of newly encountered words and discuss mathematics, science, and other subjects. The two brothers and sister were all supportive and very helpful to each other. Whilst this was admirable and encouraging, it would often entail them walking back and forth, from one of their rooms to another room. This was rather disruptive at times. Copyright ©2021.Some Rights Reserved. faspassmaths.com 49
On occasions, when they were engaged in school projects, there would be extra materials lying around, and their respective rooms would become rather overcrowded and inconvenient for comfortable work. Dad and Mom spoke with all three children. They thought that the Sandiford home needed a special room for study purposes and which would do much to reduce all these problems. This study place would allow the children to comfortably do their homework and school projects, read the newspapers, make clippings for their scrapbook and use the available reference books from the family library. All these activities would now be accomplished with greater ease, increased comfort, and certainly more convenience. It would even be a relaxing room for Mom and Dad to read the newspapers, their subscribed monthly magazines and journals and even help the children with their school work from time to time. Mom and Dad had begun to formulate plans for this project. The house already had a room that was used as a storage room. Dad decided to buy a pre-fabricated storage shed and have it adjoined to the back of the house. All the items kept in the present storage room would be transferred to this shed, with the room now to be converted into the much-desired study room. Copyright ©2021.Some Rights Reserved. faspassmaths.com 50
Everyone agreed that the idea was sound and looked forward to it being implemented. Dad was able to immediately supply the cost of some of the project items. The cost of the storage shed was $ 6 700 and the transport and installation fees would be $2 000. The total for this portion of the project would, therefore, be $8700. When the items are transferred to the new storage shed, the former storage room would need to be repainted. They decided that the floors would also need to be tiled and an air condition unit installed. The room would then be furnished with bookshelves, desks, chairs, tables and other suitable furniture. Mom and Dad wished it to be comfortable and suitable for relaxation as well as study. The children immediately loved the idea of what they envisioned the study room would become, and all volunteered to assist as much as possible, to reduce the overall cost. Copyright ©2021.Some Rights Reserved. faspassmaths.com 51
The next morning, the entire family went shopping for the furniture needed for the room. They all had good ideas for the items that were needed. At the store, chairs and desks were chosen to comfortably accommodate the different heights and sizes of the children. The family also chose some additional furniture for the study. A list of all the items needed was made, and these would be purchased at a later date, upon closer to the completion of the room. Mom and Dad suggested that the furniture should be installed in the room, only after it is completed. The list and cost of the furniture chosen were as follows: LIST Cost of large desk = $1000 Cost of revolving chair = $ 600 Cost of large wooden table = $ 900 3 small desks at $200 each = $ 600 3 chairs at $180 each = $ 540 2 recliner chairs at $600 each = $1200 Total Cost = $4840 The total cost was four thousand and eight hundred and forty dollars. Barton was asked to calculate the cost of painting the walls and the cost of tiling the floor. He first measured the dimensions of the room. The room was rectangular and had two walls that measured 8 metres by 3 metres and two walls that measured 5 metres by 3 metres. Copyright ©2021.Some Rights Reserved. faspassmaths.com 52
The height of the room was three metres and the total area to be painted was seventy-eight square metres. This excluded the ceiling which was considered to be in pristine condition and so would not require painting. The paint was sold in pails, each costing $100. Each pail contained enough paint to cover an area of 20 square metres. Barton calculated that it would require four pails to complete the job. They would also need to purchase three paintbrushes at $20 each. The children had decided to paint the walls of the room for themselves. The cost of painting the room would, therefore, be the cost of only the paint supplies, which amounted to $460. The area of the floor was 40 square metres and would be covered with square tiles of side 40 centimetres. The number of tiles required would be 250 and the cost was $10 for each tile. A skilled worker would have to install the tiles. The cost of installation was $2 per tile. The entire job of tiling the floor would amount to $3 000. The price of the air condition unit was $3000 and the installation fee was $1000 and was inclusive of the electrical work and the labour. The cost of air conditioning amounted to $4 000. The list of expenses to convert the storage room to the study was now going to be, LIST of expenditure Total cost of installing the pre-fabricated shed = $ 8 700 Total cost of all furniture = $ 4 840 Total cost of painting walls = $ 460 Total cost of tiling the floor = $ 3 000 Total cost of installing the A/C unit = $ 4 000 Copyright ©2021.Some Rights Reserved. faspassmaths.com 53 Total cost of the entire project = $21 000
The total cost of the project was $21 000. Dad decided that he would withdraw $6 000 from the family’s savings account at the bank to cover part of the cost and would take a loan to cover the remainder which would be $15 000. The children listened attentively to Dad and Mom’s plans and soon work was on the way. The local bank had approved the loan at the rate of 10% per annum simple interest. Dad was allowed to choose a repayment period of 1 year or 18 months or 2 years. Barton calculated that the simple interest on the sum of $15 000, when borrowed for 1 year at the rate of 10 % simple interest, would be $1 500. Copyright ©2021.Some Rights Reserved. faspassmaths.com 54
The total that would have to be repaid would be $16 500 and the equal monthly instalments would be $1 375. However, if the loan was taken for a period of 18 months, the simple interest would be $2 250 and the total amount to be repaid would be $17 250. The equal monthly instalments would now be reduced to $958.33. Then, if Dad chose to repay the loan in the longest allowable time of 2 years, the total simple interest would be $3 000 and the total amount to be repaid would be $18 000. The equal monthly instalments would then be further reduced to be $750. Dad preferred a monthly instalment that did not exceed $900 per month and so his choice was to take the loan for two years. For the next few days, all the work for the new study room went according to plan and all the family members helped in whatever way they could. They would all benefit greatly. It was not too long afterwards that Barton, his siblings and sometimes their parents were all enjoying the pleasure and comfort of their new study room. It is so wonderful to have a separate study room at home, thought Barton. Maybe all houses should have one, he thought, with his well- meant intention and childish innocence.
