Lesson details
Key learning points

- If one part is decreased and the other is increased by the same amount, the whole stays the same.
- Redistributing between parts with the whole staying the same is sometimes known as the 'same sum' rule.
Keywords
Whole - The whole is all the parts or everything, the total amount.

Common misconception
The brackets are intended to make it easier for pupils to distinguish between different parts of the expression. Brackets are unfamiliar to learners so may cause errors.
If the brackets lead to confusion then remove them and use colour or some other signifier. Pupils needs to be able to see, understand and analyse any changes through redistribution.
