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

Keywords

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.

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.

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