Task# Link-Cube Addition

Illustrative MathematicsVaries

The purpose of this task is for students to identify and represent related addition and subtraction equations with objects and equations. While there are eight possible equations for every pair of numbers rolled that are different, students do not need to write all eight equations every time. A task that explicitly asks students to write all eight equations is 1.OA Fact Families with Pictures. A good follow-up to this task is 1.OA Fact Families.
