Lesson details
Key learning points
- 10 is double 5, so when the products are the same, the factor × 10 is half of the factor × 5
- When we multiply the same factor by 5 and 10, the product of the factor × 10 is double the product of the factor × 5
- 5 is half of 10, so when the products are the same, the factor × 5 is double the factor × 10
- When we multiply the same factor by 5 and 10, the product of the factor × 5 is half of the product of the factor × 10
Keywords
Product - A product is the result of two or more numbers multiplied together.
Factor - A factor is a number which exactly divides another whole number.
Double - To become twice as many / to multiply by two.
Half - One of two equal parts of a whole. To divide into two equal parts.
Common misconception
Children may incorrectly double or halve to find the missing products or factors.
The use of counters or visuals will help children to see the relationship between 10 and 5 in each context and support them to know when they must use doubling and when they must use halving.
