Subtraction facts from subtract 1 to subtract 12

Choose a subtraction family below. Every fact is shown beside the addition fact that checks it, so a child can use what is already known to find the answer.

Subtraction is easiest when it is taught as addition seen backward. If a child knows that 7 + 8 = 15, then 15 - 7 and 15 - 8 are already half learned. Start with subtract 1, 2 and 10, then work through the rest.
