Lesson details

Key learning points

  1. Recall odd and even numbers to ten.
  2. A number is even if the ones digit is even.
  3. An even number can be made from groups of two.
  4. A number is odd if the ones digit is odd.
  5. An odd number cannot be made from groups of two.

Common misconception

Children may think a number is an odd number if the tens digit is odd.

Reinforce the tens number being even by showing the groups of 2 We only need to look at the ones digit to see if a number is odd or even.

Keywords

  • Odd - Any number that cannot be made of pairs. The last digit is 1, 3, 5, 7 or 9

  • Even - Any number that can be made of pairs. The last digit is 0, 2, 4, 6 or 8

  • Pair - Two together. Often with something in common.

Give children experience of odd and even numbers in different contexts and using different representations. Look for patterns and similarities and differences.
