# Use knowledge of multiplication to calcuate the product

I can use knowledge of multiplication to calculate the product.

## Lesson details

### Key learning points

- If you know the number of groups and the group size you can work out the overall number.
- If you know the factors you can calculate the product.
- You can skip count in the group size to calculate the product.

### Common misconception

Children may confuse how to find the product (total amount)

Model use of terminology - ask children what various parts of the multiplication equation represents. E.g. 'The 2 represents how many coins there are.' ' The 5 represents the value of each coin.' 'That is the same as 5, 2 times.

### Keywords

Skip count - Counting in steps of equal size. For example, skip counting in twos means to count in equal steps of two.

This lesson explores finding the product through the context of money, particularly using the 2p 5p and 10 p. Where possible practice skip counting in 2s 5s and 10s especially in the context of coins where pupils may be less familiar.
