Lesson details

Key learning points

  1. Odd and even numbers alternate.
  2. Between two even numbers there is an odd number.
  3. Between two odd numbers there is an even number.
  4. Identify odd and even numbers using both the number names and numerals.

Common misconception

Children may see the pairs in an odd number and think it is an even number.

Ensure children are looking for the extra one that makes a number odd. Provide opportunities to group other odd sets e.g. pairs of socks, pairs of hands / feet and realising an odd number always has an 'odd' one.
