Fact Families

fact family

Next week in Maths we will be exploring addition and subtraction again.  The children will learn about how they can use the ‘inverse’ to find missing numbers and to create fact families.

We make fact families using three numbers that work together to give 4 number sentences that are all true.  Below is an example of a fact family:

34 + 14 = 48

14 + 34 = 48

48 – 14 = 34

48 – 34 = 14

If the children are given a number sentence 34 + 14 = 48 and are asked to find the missing number in 48 – ___ = 34, they should make the connection that the missing number is 14 because they know that 48 – 34 = 14 & 14 + 34 = 48.

Check out the following game where the children can practise making fact families for addition and subtraction.  http://www.topmarks.co.uk/number-facts/number-fact-families

(They can also practise making them for multiplication and division if they want to.)
