Answer to Question 1 (4 marks)
1. Go to the top of the blue bar and read across to the scale: 14 children chose blue (1 mark).
2. The shortest bar is green, at 6, so green is the least popular colour (1 mark).
3. Blue has 14 and red has 8: 14 − 8 = 6 more children chose blue (1 mark).
4. Read every bar: red 8, blue 14, green 6, yellow 10. Add them: 8 + 14 = 22, 22 + 6 = 28, 28 + 10 = 38 children (1 mark).
Answer to Question 2 (4 marks)
1. Bea has 5 full circles and each full circle is 5 books: 5 × 5 = 25 books (1 mark).
2. Ali has 3 full circles: 3 × 5 = 15 books (1 mark).
3. Cal has 2 full circles, which is 2 × 5 = 10 books. Add all three children: 15 + 25 + 10 = 50 books. No half circles appear, so there are no 2.5 values to add (2 marks: 1 for Cal = 10, 1 for 50).
Answer to Question 3 (4 marks)
1. 55 °C (1 mark).
2. 90 − 70 = 20 °C (1 mark).
3. The line is steepest from 0 to 5 minutes (a fall of 20): 0 to 5 minutes (1 mark).
4. The line is not completely flat: it still falls by 5 °C from 15 to 20 minutes, but it falls more slowly (1 mark).
Answer to Question 4 (4 marks)
1. A scale of 5 per square is good: 65 needs 13 squares, or a scale of 10 per square: 6.5 squares (1 mark for a good choice, 1 mark for a reason). A scale of 1 would need 65 squares: too many.
2. 35 ÷ 5 = 7 squares (1 mark).
3. 20 + 35 + 50 + 65 = 170 (1 mark).
Answer to Question 5 (4 marks)
1. The biggest number in the table is 30, so Cara swam the most lengths. Dan swam 12, so the difference is 30 − 12 = 18 lengths (2 marks: 1 for Cara, 1 for 18).
2. Ben swam 18 lengths of 25 m: 18 × 25 = 10 × 25 + 8 × 25 = 250 + 200 = 450 m (1 mark).
3. Total: 24 + 18 + 30 + 12 = 84 lengths. 84 is less than 100, so no, they did not reach the target; they were 16 lengths short (1 mark).

Total : 20 marks
