Lesson details
Key learning points
- 5 groups of 2 can be said as 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.
Keywords
Commutative - Multiplication is commutative. This means the order of the factors can be changed without changing the calculation or product.
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 confuse identifying the number of groups and group size.
Use sentence stems to support children's thinking and model writing the equation, e.g. for 2 groups of 5 we can say 2 × 5 For 5, two times we can say 5 × 2
