1st Grade Math Practice

Addition and subtraction undo each other, so they are practiced side by side here. Start with single-digit facts.

Addition

4 + 5 = 9
5 + 4 = 9

Subtraction

9 − 5 = 4
9 − 4 = 5

4 and 5 are the parts. 9 is the whole. Subtraction starts from the whole and takes away one part.
