I can recall doubles within 10

## Lesson details

### Key learning points

- When we double, we add two equal addends.
- When we halve, we subtract one of the equal amounts from its double.
- Halving is the inverse of doubling.
- If I know double 4 is 8, I know half of 8 is 4

### Common misconception

Children may struggle to see that a double is two of the same thing.

Spend time exploring doubles that can be found in the children's immediate environment e.g. using their hands or playing a game of dominoes.

### Keywords

Double / Doubling - To become twice as many.

Half - One of two equal parts of a whole.

Halving - To divide into two equal parts.

Representations of doubles should be displayed around the classroom for children to refer to when recalling. Ultimately, our aim is to support children to learn these facts to the point of automaticity.
