Grade 3 · Math · Unit 5 of 12
Division
Sharing and grouping
What your child practises
Understanding division as sharing fairly and as making equal groups, and using multiplication facts to divide (3 × 4 = 12, so 12 ÷ 3 = 4).
BC Curriculum learning standard: Multiplication and division concepts: division as equal sharing and equal grouping
How we explain it
Children can open this short lesson before they practise.
- 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
What number goes in the box?
3 × = 12
- 4
- 5
- 3
- 9
Show answer
4
Hint: Count by 3s until you reach 12: 3, 6, 9, 12. How many 3s did you count?
Question 2
What is 12 ÷ 4?
12 ÷ 4 = ?
- 2
- 8
- 3
- 4
Show answer
3
Hint: Think multiplication: 4 × ? = 12. Count by 4s to 12: 4, 8, 12. That's 3 jumps.
Question 3
What is 10 ÷ 2?
10 ÷ 2 = ?
answer box

5
Hint: Think multiplication: 2 × ? = 10. Count by 2s to 10: 2, 4, 6, 8, 10. That's 5 jumps.

Hint: Share them out one at a time, like dealing cards, until they're all gone. Or think: 5 × ? = 25. 5 × 5 = 25.
Question 5
2 × 5 = 10. So what is 10 ÷ 2?
10 ÷ 2 = ?
- 2
- 6
- 5
- 4
Show answer
5
Hint: Multiplying and dividing undo each other. 2 groups of 5 make 10, so 10 split into 2 groups is 5.
Question 6
