## Lesson details

### Key learning points

- Partitioning the dividend into tens and ones helps when dividing a 2-digit by a 1-digit number.
- If the dividend is not a multiple of the divisor, there will be a remainder.
- If the remainder is a number of tens, you can regroup the tens for ones and continue to divide.

### Common misconception

Pupils not being able to regroup when dividing.

Use concrete resources to highlight regrouping of tens. Ask children 'What is the highest multiple you know?' to support with partitioning.

### Keywords

Partition / partitioning - Splitting a number into smaller parts.
