Lesson details

Key learning points

Identify the group size and the number of groups in the problem.
If you know the factors you can calculate the product.
You can skip count in the group size to calculate the product.

Keywords

Product - A product is the result of two or more numbers multiplied together.
Factor - A factor is a number which exactly divides another whole number.

Common misconception

Pupils may find it difficult to identify the factors in the word problems.

Model how to address questions. Use of familiar stem sentences to support pupils in identifying the factors: 'There are 7 bamboos. Each bamboo is a length of 5 m. 7 is factor and 5 is factor. We can skip count in ___ to find the product.'

This lesson consists of solving multiplication problems in measures - a quick reminder of cm and m will help children to establish the size difference. Encourage children to use stem sentences to articulate their thinking. Provide pupils with number lines if they are struggling to skip count.
