## Lesson details

### Key learning points

1. When both addends are equal, we are doubling.
3. Doubling a whole number always gives an even number.

### 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.

• Equal - Exactly the same amount or value.
