1. Answer to Question 1

   1. Line the start of the strip up with 0 and read where it ends. The first strip ends at the 5 mark, so it is 5 cm long.
   2. The second strip also starts at 0 and ends at the 9 mark, so it is 9 cm long.
   3. Find the difference: 9 − 5 = 4 cm. Check by counting on from 5: 6, 7, 8, 9 is 4 steps.

2. Answer to Question 2

   1. 2 × 100 = 200 cm.
   2. 300 ÷ 100 = 3 m.
   3. 5 × 100 = 500 cm.
   4. 400 ÷ 100 = 4 m.
   5. 100 + 50 = 150 cm.

3. Answer to Question 3

   1. 2 × 1000 = 2000 g.
   2. 3000 ÷ 1000 = 3 kg.
   3. 500 + 500 = 1000 g = 1 kg.
   4. 1000 − 400 = 600 g.
   5. 5 × 1000 = 5000 g.

4. Answer to Question 4

   1. Each litre is 1000 ml, so 3 litres is 1000 + 1000 + 1000 = 3000 ml.
   2. Count how many lots of 1000 ml fit in 4000 ml: 1000, 2000, 3000, 4000. That is 4 litres.
   3. Add the two jugs: 250 ml + 250 ml = 500 ml, which is half a litre.
   4. 1 litre is 1000 ml. Take away the 600 ml poured out: 1000 − 600 = 400 ml left in the bottle.

5. Answer to Question 5

   1. cm: a pencil is about 15 cm.
   2. m: a house is about 8 m tall.
   3. g: a pencil is about 5 g.
   4. kg: a dog is about 10 kg.
   5. ml: a teaspoon holds about 5 ml.
   6. l: a swimming pool holds thousands of litres.

6. Answer to Question 6

   1. 35 is less than 53, so 35 cm < 53 cm.
   2. 2 kg = 2000 g, so 2 kg = 2000 g.
   3. 1 l = 1000 ml, and 500 is less than 1000: 500 ml < 1 l.
   4. 1 kg = 1000 g, and 90 is less than 1000: 90 g < 1 kg.
   5. 1 m = 100 cm, and 150 is more than 100: 150 cm > 1 m.

7. Answer to Question 7

   1. 3 × 100 = 300 cm.
   2. 300 − 120 = 180 cm.
   3. 2 m = 200 cm. 200 − 185 = 15 cm short.
   4. 185 cm is greater than 120 cm, so yes, Mia is right.

8. Answer to Question 8

   1. 10 + 4 = 14 kg.
   2. 10 − 3 = 7 kg.
   3. 4 − 2 = 2 kg.
   4. 3 + 2 = 5 kg. 5 × 1000 = 5000 g.

9. Answer to Question 9

   1. 250 + 200 + 150 = 450 + 150 = 600 g.
   2. 300 + 100 = 400 ml.
   3. 1000 − 250 = 750 g.
   4. 1000 − 300 = 700 ml.

10. Answer to Question 10

    1. The longest jump is 160 cm, so Carl wins.
    2. The shortest jump is 128 cm, so Dina comes last.
    3. 160 − 128 = 32 cm further.
    4. 128 cm, 132 cm, 145 cm, 160 cm.

11. Answer to Question 11

    1. Each bucket holds 5 litres. Count in 5s for 8 buckets: 5, 10, 15, 20, 25, 30, 35, 40. So 8 × 5 = 40 litres.
    2. Add the warm water from the jug: 40 + 2 = 42 litres.
    3. 3 litres splash out, so subtract: 42 − 3 = 39 litres left in the pool.
    4. The pool holds 50 litres. Count on from 39 to 50: 1 to reach 40, then 10 more. 1 + 10 = 11 litres are needed.

12. Answer to Question 12

    1. The temperature goes up by 9 degrees from 4 °C: 4 + 9 = 13 °C at lunchtime.
    2. At home time it is 5 degrees lower than 13 °C: 13 − 5 = 8 °C.
    3. Tuesday was 6 °C and Monday was 4 °C at nine o'clock. 6 is higher than 4, so Tuesday was warmer, by 6 − 4 = 2 degrees.
    4. Water turns into ice at 0 °C. Below 0 °C puddles can freeze.

13. Answer to Question 13

    1. 2 m = 200 cm.
    2. 85 + 70 = 155 cm.
    3. 200 − 155 = 45 cm.
    4. The fact books are 60 cm and only 45 cm is left. 60 is greater than 45, so they will not fit. They are 15 cm too long.

14. Answer to Question 14

    1. 2 × 1000 = 2000 ml.
    2. 6 × 250 = 1500 ml.
    3. 2000 − 1500 = 500 ml left.
    4. 500 ÷ 250 = 2 cups, because 2 × 250 = 500.

15. Answer to Question 15

    1. 6 × 500 = 3000 ml, which is 3 litres.
    2. 3 × 2 = 6 kg.
    3. 4 × 150 = 600 cm, which is 6 m.
    4. 30 × 100 = 3000 ml. The children drink 3000 ml and there is 3000 ml. Yes, there is just enough.
    5. 3000 − 3000 = 0 ml left. None is left and none more is needed.

16. Answer to Question 16

    1. 4 × 90 = 360 cm.
    2. 3 × 100 = 300 cm.
    3. 3 × 90 = 270 cm, and 4 × 90 = 360 cm is too long. He can cut 3 shelves and 300 − 270 = 30 cm is left over. The 4th shelf needs a second plank.
    4. 2 × 160 = 320 cm.
    5. Shelves 360 cm + sides 320 cm = 680 cm. Two planks are 600 cm, and 680 is greater than 600, so Grandad is not right. He needs 80 cm more.

17. Answer to Question 17

    1. 2 + 1 = 3 kg.
    2. 3000 ÷ 500 = 6 small bags.
    3. 3 × 1000 = 3000 g.
    4. 2 × 500 = 1000 g, which is 1 kg.
    5. 3 − 1 = 2 kg are left.

18. Answer to Question 18

    1. 80 + 45 + 15 = 140 litres.
    2. 80 ÷ 10 = 8 buckets.
    3. 31 − 18 = 13 degrees.
    4. Elephants and monkeys together: 80 + 15 = 95 litres. 45 is less than 95, so he is not right.

19. Answer to Question 19

    1. 31 − 12 = 19 cm.
    2. Week 1 to 2: 19 cm. Week 2 to 3: 58 − 31 = 27 cm. Week 3 to 4: 90 − 58 = 32 cm. The most growth is between week 3 and week 4 (32 cm).
    3. 100 − 90 = 10 cm.
    4. Each week the plant grows more than 10 cm, so by week 5 it will be taller than 1 m. Yes, she is likely to be right.

20. Answer to Question 20

    1. 2 kg = 2000 g. 2000 ÷ 4 = 500 g for each book.
    2. 4 × 200 = 800 ml. 1000 − 800 = 200 ml left.
    3. 5 m = 500 cm. 500 is more than 450, so Zara is right.
    4. Write all in cm: 100, 90, 105, 95. In order: 90 cm, 95 cm, 1 m, 1 m 5 cm.
