Fact Families

During Calendar Math each day, we have been working on Fact Families. Fact families are a set of facts, each of which relates the same three numbers through addition or subtraction. Examples: 3 + 7 = 10, 7 + 3 = 10, 10 - 7 = 3, 10 - 3 = 7. Click here to read a very helpful and informative article by Amanda Moran.

Our Fact Family board we use in Calendar Math.

Here is a link to a Fact Family game we play during Calendar Math.
