How we explain it
Children can open this short lesson before they practice.
- Dividing shares things equally or makes equal groups.
- Think of the multiplication fact that goes with it.
- Ask: what times the divisor makes the number?
Example: 20 ÷ 4 = ? What times 4 makes 20? 4 × 5 = 20. Answer: 5

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
4 × 2 = 8. So what is 8 ÷ 4?
8 ÷ 4 = ?
- 4
- 1
- 3
- 2
2
Hint: Multiplying and dividing undo each other. 4 groups of 2 make 8, so 8 split into 4 groups is 2.
Question 2
What number goes in the box?
3 × = 15
- 5
- 4
- 6
- 12
5
Hint: Count by 3s until you reach 15: 3, 6, 9, 12, 15. How many 3s did you count?
Question 3
What is 8 ÷ 4?
8 ÷ 4 = ?
answer box
2
Hint: Think multiplication: 4 × ? = 8. Count by 4s to 8: 4, 8. That's 2 jumps.
Question 4
There are 25 cookies. Each bag gets 5. How many bags are needed?
🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪- 6
- 5
- 4
- 7

Hint: Make groups of 5. Count by 5s up to 25: 5, 10, 15, 20, 25. That's 5 bags.
Question 5
Which number sentence matches the story?
20 apples are shared equally into 5 baskets.
How many go in each basket?
- 20 − 5
- 20 × 5
- 20 ÷ 5
- 20 + 5
20 ÷ 5
Hint: Sharing equally into groups is division: 20 things ÷ 5 groups.
Question 6
