- Split a number into easy parts.
- Division is the opposite of multiplication.

Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
Which fact is in the same fact family as 8 × 7 = 56?
- 56 ÷ 7 = 7
- 56 ÷ 8 = 7
- 56 − 8 = 48
- 8 + 7 = 15
Show answer
56 ÷ 8 = 7
Hint: A fact family uses the same three numbers: 8, 7 and 56. Division undoes multiplication, so 56 ÷ 8 = 7.
Question 2
What is 9 × 4?
9 × 4 = ?
- 36
- 32
- 40
- 45
Show answer
36
Hint: Use 10s: 10 × 4 = 40, then take away one 4. So 9 × 4 = 36.
