## Lesson details

### Key learning points

1. If the tens number is not a multiple of the divisor then the remainder is recorded next to the ones digit.
2. If there is a remainder after dividing the tens digit the tens are regrouped and the ones digit becomes a 2-digit number
3. If the number of ones, including any regrouped tens, is a multiple of the divisor, there will be no remainder.

### Common misconception

Pupils not understanding and/or recording the regrouped amount.

Continue to use language of unitisation. For example '7 tens ÷ 3 is 2 tens remainder 1 ten.' Ask what the regrouped amount represents.

### Keywords

• Regroup / regrouping - The process of unitising and exchanging between place values is known as regrouping.

Encourage pupils to think about remainders by playing odd one out based on multiples. Remind pupils that if the number of ones, including any exchanged tens, is not a multiple of the divisor, there will be a remainder.
