I can use a range of strategies to solve division problems

## Lesson details

### Key learning points

- Look at the dividend and divisor to decide which strategy is most effective and explain why.
- Use partitioning if the dividend can be partitioned into multiples of the divisor.
- Use short division if the dividend cannot be partitioned into multiples of the divisor.

### Common misconception

Pupils may always choose short division to solve division equations.

Encourage pupils to think about other strategies that they know. Ask questions such as 'Is this the most efficient method?'

### Keywords

Short division - Is a formal method of division often used when dividing any number by a one digit number.

Partition - Partition means splitting a number into smaller parts.

A quick recap of strategies for division at the beginning of the lesson will be helpful. It is important that pupils understand that there may not always be one best approach. Encourage debate as to why one method may be more efficient than another.
