Lesson details

Key learning points

  1. When we multiply the same factor by 5 and 10, the product of the factor × 10 is double the product of the factor x 5
  2. 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
  3. When the products are the same, the factor × 5 is double the factor × 10
  4. When the products are the same, the factor × 5 is half of the factor × 10

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.

Keywords

  • Factor - A factor is a number which exactly divides another whole number.

  • Product - A product is the result of two or more numbers multiplied together.

  • 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.

Continually emphasise the idea that 2 fives are equal to 1 ten and 1 ten is equal to 2 fives to support children's understanding of why doubling and halving is used to calculate multiples of 10 and 5
