# Divide using partitioning and representations (multiple regroups and remainder)

I can divide using partitioning and representations (multiple regroups and remainder)

## 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.
- If the ones number is not a multiple of the divisor then there will be a remainder in the answer.
- Regrouping and remainders can be represented practically using place value counters.

### Common misconception

Pupils may not regroup correctly.

Ask pupils what each digit represents. Continue to use skip counting when dividing each digit in the dividend.

### Keywords

Remainder - A remainder is an amount left over after division.

Partitioning - Partition means splitting a number into parts.

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

Begin by playing a game which encourages pupils to think of the highest multiple they know of a number. During the lesson, pupils should use part whole models to partition into parts that are helpful for the division equation.
