# Represent multiplication equations in different ways

I can represent multiplication equations in different ways.

## Lesson details

### Key learning points

- The same multiplication can be represented in two different ways.
- If you have 5 groups of 2 you have 2 five times so 5 x 2 = 2 x 5
- Factor pairs can be written in any order.
- You can say that multiplication is commutative.

### Common misconception

Pupils may confuse the number of groups and group size.

Continue to use the number stems and arrays to highlight the relationship between the factors and products.

### Keywords

Commutative - An operation is commutative if the values it is operating on can be written in either order without changing the calculation.

Factor pairs - A set of two factors, which, when multiplied together, give a particular product.

Continue to chorally chant the 2, 5 and 10 times tables at any given opportunity.
