Lesson details

Key learning points

  1. Five is half of ten
  2. Multiples of 5 are half the value of multiples of 10
  3. Ten is double 5
  4. Multiples of 10 are double the value of multiples of 5

Keywords

  • Related - The relationship between a set of values.

  • 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

Pupils may assume that all multiples of 5 are multiples of 10

Show children the relationship between 5s and 10s using the multiplication chart and number line. Make clear the relationship between the multiples of 5 and 10 through using stem sentences; for every one group of ten, there are two groups of 5

Continue to chorally rehearse 5 and 10 times tables. Pupils should become increasingly more fluent.
