Missing Number Problems

Do you remember learning about fact families last week in big maths?  Well that will come in useful today.

Take a look at the missing number problems on page 27 of your pupil maths book.  Some of the questions are easy to figure out using a numberline but some are a bit more tricky.  Why not try writing out a fact family to help you find the answer?

Here is an example:

6 + ? = 13

I'm not sure what the answer is so i'm going to turn this calculation into a fact family to help me.  Remember a fact family uses the same 3 numbers to make 2 additions and 2 subtractions.

6 + ? = 13

? + 6 = 13

13 - ? = 6

13 - 6 = ?

I think the subtraction calculation at the bottom is the easiest one to work out so I will now use my numberline to find the answer.  The answer is 7
