# Explain that the addends can be added in any order

I can explain that the addends can be added in any order.

## Lesson details

### Key learning points

- When we add three numbers, the sum will be the same whichever pair of addends we add first.
- The order of the addends can change and the sum will stay the same.

### Common misconception

Children may not understand that either pair of addends can be added first and the sum will remain the same.

Use concrete materials to represent the addends for children to explore, discussing what is the same (the addends) and what is different (the pair being added first).

### Keywords

Addends - Any numbers that are added together.

Efficient - Not wasting time or effort. An efficient strategy is one we can carry out easily.

Strategy - A plan or method to achieve a specific goal.
