Explain how a multiplication equation with 2 as a factor is related to doubling
Lesson details
Learning outcome
I can explain how a multiplication equation with 2 as a factor is related to doubling.
Key learning points
- If 2 is a factor, you can use doubles facts to solve the problem.
- 2 could represent the group size or the number of groups.
- Identify the group size and the number of groups in the multiplication story.
Keywords
Double / doubling - To become twice as many / to multiply by two.
Common misconception
Children may not grasp why 5 + 5 is equal to 2 × 5
Continue to use the stem sentences to help children understand doubling; 5 + 5 is the same as 2 groups of 5. This is the same as 2 × 5. Children can use a 2 times table chart to help them answer questions.
Teacher tip
At this point, children know doubling as an additive structure. They will now be able to represent a doubles addition equation as a multiplication equation. Remind children that doubling is the same as multiplying by 2
