**Title:** Fact Families

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students use books and connecting cubes to explore the relationship of addition to subtraction. Students search for related addition and subtraction facts for a given number using a virtual or actual calculator to find differences. They also investigate fact families when one addend is 0 as well as when the addends are the same. Several pieces of literature appropriate for use with this lesson are suggested.
