Remember when we subtract the number always gets smaller; we count backwards.
Minus, take-away, less than and subtract all mean the same thing.
Warm Up:
Go on a number hunt around your house. Can you identify the number before the number you find? Remember to find the number before, you must subtract 1.

Extra Challenge:
Can you answer these missing number sums. Remember they are take away sums:
· 7 – ? = 7
· 9 – ? = 6
· 13 – ? = 10
· 10 – ? = 8
· 8 – ? = 0
· 17 – ? = 13
