Lesson details
Key learning points
- If one factor is made ten times the size, the product will be ten times the size.
- One factor has been multiplied by 10 so the product is multiplied by 10
- When multiplying two numbers, if either factor is made 10 times the size, the product will be 10 times the size.
- 6 multiplied by 30 is equal to 60 multiplied by 3 or 6 tens multiplied by 3
Common misconception
Place value counters don't have proportionality in the same way that Base 10 does which can make the concepts here more abstract.
Smaller multiplications can be used with Base 10 to model scaling to start off with. Try 2 × 1 or 3 × 1 scaling up to become 2 × 10 or 3 × 10 with Base 10 and then put this modelling side-by-side with place value counters to make the links.
Keywords
