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