Level 1 · Warm-up
1 8 × 7 = ?
Show worked solution
8 × 7 = 56. (8 × 6 = 48, and 48 + 8 = 56.)
2 Double 26.
Show worked solution
Double 20 is 40 and double 6 is 12, so 40 + 12 = 52.
3 4 × 9 = ?
Show worked solution
4 × 9 = 36. (Double 9 is 18, double again is 36.)
Level 2 · Core
4 How many legs altogether on 6 spiders (8 legs each) and 3 beetles (6 legs each)?
Show worked solution
Spiders: 6 × 8 = 48. Beetles: 3 × 6 = 18. Altogether 48 + 18 = 66 legs.
5 ▢ × 4 = 32. What number belongs in the box?
Show worked solution
32 ÷ 4 = 8, because 8 × 4 = 32.
6 You know that 8 × 6 = 48. Use it to work out 8 × 12.
Show worked solution
Doubling one of the numbers doubles the answer: 48 doubled is 96.
Level 3 · Challenge
7 Ice blocks come in packs of 8. A teacher needs 50. How many packs must she buy?
Show worked solution
50 ÷ 8 = 6 remainder 2. Six packs is only 48, so she needs 7 packs.
8 A number is doubled, then doubled again, then doubled once more, giving 96. What was the number?
Show worked solution
Halve three times: 96 → 48 → 24 → 12. (12 × 8 = 96.)
9 Which is bigger: 4 × 18 or 8 × 8? Write the bigger answer as a number.
Show worked solution
4 × 18 = 72 and 8 × 8 = 64, so the bigger answer is 72.
