  1. YEAR 2 Statistics Draw pictograms (2, 5, 10) Interpret pictograms (2, 5, 10) Block Diagrams Block 2 – Week 4

  2. Lesson 1 Step: Draw Pictograms (Practical)

  3. Fluency Choose an appropriate key and complete the pictogram. 2 KEY: = 2 would be an appropriate key as it would require less counting than using a key of 1.

  4. Fluency Choose an appropriate key and complete the pictogram. 10 KEY: = 10 would be an appropriate key as the numbers are larger.

  5. Fluency Choose an appropriate key and complete the pictogram. 5 KEY: = 5 would be an appropriate key as the numbers end in 0 and 5.

  6. Reasoning The best key to use for a pictogram is 5. True or false? False. 9 is not divisible by 5.We also cannot use a half symbol to represent it. What is the best key to use? The best key to use would be 2. Create a pictogram to show this.

  7. Problem solving Which key has been used on the pictogram below? Explain how you know. KEY: = 2

  8. Lesson 2 Step: Draw Pictograms (2, 5, 10)

  9. Fluency Complete the pictogram using the key to help you. KEY: = 2

  10. Fluency Complete the pictogram using the key to help you. KEY: = 2

  11. Fluency Complete the pictogram using the key to help you. KEY: = 5

  12. Fluency Complete the pictogram using the key to help you. KEY: = 5

  13. Fluency Complete the pictogram using the key to help you. KEY: = 10

  14. Fluency Complete the pictogram using the key to help you. KEY: = 10

  15. Reasoning Spot the mistake and explain your answer. KEY: = 5 25 30 15 4 The total of pink should be 20 as the key shows each triangleis worth 5. (4 x 5 = 20).

  16. Problem solving Use the clues to complete the pictogram. KEY: = 10 100 80 50 There are double the amount of blue than green.There are 20 less red than blue.

  17. Lesson 3 Step: Interpret pictograms (2, 5, 10)

  18. Fluency KEY: = 2 a) How many people have blonde hair? _________ b) Find the difference between people with ginger hair and black. _________ c) How many more people with brown hair than black? _________ 15 11 5

  19. Fluency KEY: = 2 a) What is the total number of lions? _________ b) Find the difference between the giraffes and elephants. _________ c) How many fewer rhinos than lions? _________ 14 13 3

  20. Fluency KEY: = 5 a) What is the total number of grapes? _________ b) Find the difference between the bananas and apples. _________ c) How many more grapes than oranges? _________ 40 25 15

  21. Fluency KEY: = 5 a) What is the total number of horses? _________ b) Find the difference between the pigs and chickens. _________ c) What is the combined total of cows and chickens? _________ 45 20 40

  22. Fluency KEY: = 10 a) What is the total number of people who like strawberry? _________ b) Find the difference between chocolate and mint. _________ c) How many more like strawberry than vanilla? _________ 95 75 5

  23. Fluency KEY: = 10 a) What is the total number of people who like lemon? _________ b) Find the difference between orange and blackcurrant. _________ c) What is the combined total of strawberries and lemons? _________ 35 35 85

  24. Fluency KEY: = 2 There are _______ people who like vanilla. _______ more people prefer chocolate to strawberry. 14 8

  25. Fluency KEY: = 10 There are _______ people who like cheese. There are _______ more people who prefer pepperoni to ham. 90 30

  26. Fluency KEY: = 2 There are 8 _________ and ______ cows. There are _______ more people who prefer horses to chickens. pigs 12 6

  27. Fluency KEY: = 5 How many people like grapes? _______ There are _______ more people who prefer apples to oranges. 40 20

  28. Fluency KEY: = 10 How many elephants were there? _______ How many more lions than rhinos? _______ 80 40

  29. Reasoning The pictogram shows the number of jewellery sold. The combined total of rings and bracelets equals watches. True or false? Explain how you know. True. 70 watches, 40 rings & 30 bracelets sold. 40 + 30 = 70. KEY: =10

  30. Problem solving Complete the pictogram using the clues. KEY: = 5 1. There are 50 ash. 2. There are 5 more birch than ash. 3. There are 20 fewer elm than birch. 4. There are 15 less oak than elm.

  31. Lesson 4 Step: Block diagrams (Practical)

  32. Fluency Use the block diagram to complete the table. 7 4 2 5 1. Which is the most popular? Pencil 2. Which is the least popular? Ruler

  33. Fluency Complete the table using the block diagram. 1. How many more dogs than hamsters? 5 2. How many fewer budgies than cats? 3

  34. Fluency Complete the block diagram using the table.

  35. Reasoning Spot and explain the mistake. The table shows 6 for winter but the block diagram only shows 5 blocks.

  36. Problem solving Give the block diagram a suitable title. Use the block diagram to create your own questions for a partner to solve.

  37. Lesson 5 Step: Block diagrams

  38. Fluency Numberofsales Which season had the most sales? How many? _____________________ Which season had 12 fewer sales than summer? ______________ Summer – 18 sales Spring

  42. Fluency Number of cars What is the difference between the most and least popular? ___________ Which car colour had 50 fewer than blue? ______________ 70 Green

  43. Reasoning The block diagram represents the table below.True or false? Explain your answer. False. The table shows 40 pink but the block diagram shows 35.

  44. Problem solving Use the clues to complete the block diagram. Trousers sold the most with 90. Skirts sold 40 less than shirts which sold 30 less than trousers. There were 200 sales altogether.
