Lesson details
Key learning points
- When one factor is scaled and the other is scaled down by the same amount, the product remains the same.
- Arrays can represent the product staying the same when one factor is scaled up and the other down by the same amount.
- Scaling one factor up and the other down by the same amount maintains equivalence.
Keywords
Equivalent - Equivalent means having the same value.
Factor - A factor is a number which exactly divides another whole number.
Product - The product is the result of two or more numbers multiplied together.
Common misconception
Pupils may not select efficient ways of scaling numbers to calculate the product.
Discuss possible solutions, encouraging pupils to think about whether they can use known facts (e.g. times tables, multiples of 10) to calculate products after scaling.
