Fact Families

Students break up the blue counters into two groups that add up to 10 (for example, 3 and 7). They make up a story problem to go along with the counters. Then they fill in the fact family house with all of the possible number sentences formed by the 2 addends and the sum. Add or subtract blue counters to create fact families with sums other than 10.
