Unit 1, Lesson 7

Demonstrate the commutativity of multiplication, and practice related facts by skip-counting objects in array models

EngageNY 60 min(s)

In this lesson, students draw arrays to represent multiplication sentences, and then rotate those arrays 90 degrees to find demonstrate the commutativity of multiplication. For example, they draw an array to represent 4 × 2 = 8, and rotate the array 90 degrees to obtain an array that represents 2 × 4 = 8.
