## Lesson details

### Key learning points

- When there are two factors and one is equal to 1 then the product is equal to the other factor.
- 1 can represent the group size or the number of groups.
- Identify the group size and the number of groups in the multiplication story.

### Common misconception

Pupils may not recognise that 1 can be a factor, particularly when the context includes 1 group.

Work with children to discuss groups and what they can see, such as 3 groups of 4 Reduce the number of groups to 2 and then 1 group and identify that 1 group can still be used. Then attach this to multiplication and expressions.

### Keywords
