Use knowledge of multiplication to solve problems
Lesson details
Learning outcome
I can use knowledge of multiplication to solve problems.
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
Skip count - Counting in steps of equal size. For example, skip counting in twos means to count in equal steps of two.
Common misconception
Children may confuse group size and number of groups.
Clearly model the number of groups by demarcating groups where possible and using familiar stem sentences such as 'There are ___ groups.' Then, move onto identifying the amount of items / objects in each group. 'There are ___ in each group.'
Teacher tip
Where possible, have items presented in groups of 2s 5s and 10s to support pupils' concrete understanding of number of groups and number of items in each group. At any opportunity, continue to practice skip counting in 2s 5s and 10s.
