Unit 3, Lesson 2# Use distributive and commutative properties to relate multiplication facts where n is the unknown

EngageNY 60 min(s)

In this lesson, students apply the commutative and distributive properties in the form of the "n + 1" strategy to solve unknown facts. For example, students relate 5 × 8 and 8 × 5 and then add one more group of 8 to solve 6 × 8 and, by extension, 8 × 6.
