Check understanding
- Use addition and subtraction as inverse operations to check and solve problems
- Use multiplication and division as inverse operations to check and solve problems
- Recognise that squaring and square-rooting are inverse operations
“If your child works out '252 ÷ 7 = 36', can they immediately use the inverse to check — '36 × 7 = 252' — without having to redo the division?”
