Primary School
Well year 1 you have honestly impressed us with your fabulous maths this term. Today and tomorrow we are going to be looking at fact families and if you were in school on Friday we did this practically.
It is important that for this you use the same 3 facts and remember that...
Addition facts look like this:
part + part = whole 10 + 3 = 13 and 3 + 10 = 13
Whole = part + part 13 = 10 + 3 and 13 = 3 + 10
Subtraction facts look like this:
Whole - part = part 13 - 10 = 3 and 13 - 3 = 10
part = Whole - part 3 = 13 - 10 and 10 = 13 - 3 (Remember your whole comes in the middle here)
