In Year 2, children are encouraged to check their addition calculations. They might do this by adding the numbers up again, but in a different order. For example, if they add up 6 + 9 + 4, they may check it by recognizing that 6 + 4 makes 10, and 9 more is 19, or they may do it differently by adding 4 + 9 to make 13 then adding 6 to give 19. This is called the commutative property and means that addition calculations can be done in any order to achieve the same answer.
