What your child practises
Dividing 2- and 3-digit numbers, finding remainders and deciding what they mean in a story (round up for buses, drop the extra for full bags), and estimating with friendly numbers.

How we explain it
Children can open this short lesson before they practise.
- Divide, multiply, subtract, bring down the next digit, and repeat.
- What is left over at the end is the remainder.
- Check by multiplying back and adding the remainder.
Example: 47 ÷ 4 = ? 4 × 11 = 44. 47 − 44 = 3 left over. So 47 ÷ 4 = 11 remainder 3. Answer: 11 remainder 3
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
Divide.
117 ÷ 9 = ?
answer box
13
Hint: Think: 9 × ? = 117. Split 117 into parts that divide easily by 9, like 90 and 27.
Question 2
What is the remainder when 678 is divided by 9?
answer box
3
Hint: Find the greatest multiple of 9 that fits into 678. Subtract it from 678; what is left is the remainder.
Question 3
A ribbon is 446 cm long. How many pieces 4 cm long can be cut from it?
answer box
111
Hint: Divide. The remainder is not enough to make one more, so leave it out and use only the quotient.
Question 4
What is 127 ÷ 7?
127 ÷ 7
- 18
- 18 R 1
- 17 R 8
- 19 R 1
18 R 1
Hint: Find the greatest multiple of 7 that is not more than 127. What is left over is the remainder, and it must be less than 7.
Question 5
How can you check that 188 ÷ 4 = 47?
- Multiply 47 × 4
- Add 47 + 4
- Divide 47 ÷ 4
- Multiply 188 × 4
Multiply 47 × 4
Hint: Multiplication and division undo each other. If the quotient times the divisor gives the dividend, the division is right.
Question 6
5 friends share $285 equally. How many dollars does each friend get?
answer box
57
Hint: Sharing equally means divide by 5. Split 285 into parts that are easy to share, then add the shares.
