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.
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
