This lesson is focused on 1.OA.C.6, using the relationship between addition and subtraction, and 1.OA.B.3, applying properties of operations as strategies to add and subtract. In this lesson, students learn about fact families using dominoes. Students work to create two addition and two subtraction sentences that are related, using the same three numbers. Core Actions 2 and 3 are strongly exhibited in this lesson.
