Lesson details
Key learning points
- If the hundreds number is not a multiple of the divisor then the remainder is regrouped for tens.
- If the tens number is not a multiple of the divisor then the remainder is regrouped for ones.
- Place value resources can represent the division and the regrouping.
Common misconception
Pupils may not regroup correctly.
Encourage children to identify what each digit in the dividend represents. Ask, 'Is this digit a multiple of the divisor?'
