Fact Family Drill Cards

Flash cards for learning math fact families

We never learned about math “fact families” when I was a kid, but I thought it was a pretty neat approach. And the triangular shape of these number triads was perfect for a little triquetra.

You print these out on card stock and cut out the triangles. Each group of 3 numbers relates to each other like 5=2+3 and 5-3=2 and so on. If you’re not familiar with these, I’ve added a longer explanation on how to use the cards in the file.

This set is for addition and subtraction up to 10 (I left out the zeros as well). I now have a second set for multiplication and division too, as your math skills develop.
