Lesson details

Key learning points

  1. Multiples of 4 are double the multiples of 2
  2. Multiples of 2 are half the multiples of 4
  3. Multiples of 4 are all multiples of 2 but not all multiples of 2 are multiples of 4

Common misconception

Pupils may generalise the rule and assume that when dividing by 4 is the last digit is even, then the number is divisible by 4

Show children the relationship between 2s and 4s using the multiplication chart. Make clear that identifying the last digit as even is the first step - the last 2 digits should be a multiple of 4. Encourage discussions to highlight the relationship.

Keywords

  • Multiple - A multiple is the result of multiplying a number by another whole number.

  • Doubling - Doubling is the act of becoming twice as many.

  • Halving - Halving means to divide into two equal parts.

Continue to chorally rehearse 2s and 4s. Remind children that every integer is divisible by one.
