Identify patterns of odd and even numbers in the times tables

I can identify patterns of odd and even numbers in the times tables.

Lesson details

Key learning points

  1. When both factors are odd, the product will be odd.
  2. When one factor is odd and the other is even, the product will be even.
  3. When both factors are even, the product will be even.

Common misconception

Pupils might not recognise patterns of odd and even numbers across different times tables.

Recap what an odd and even number is. Remind children even numbers result from multiplying by even factors and odd numbers result from odd factors.

Keywords

  • Odd - An odd number is any whole number that cannot be divided exactly by 2 The ones digit is 1, 3, 5, 7 or 9

  • Even - Any whole number that can be divided exactly by 2 is an even number. The ones digit is 0, 2, 4, 6 or 8

Highlighting odd and even products in different colours can support visualisation of the patterns. Pupils may also generalise about products beyond multiplication table facts.
