Decomposing Arrays, Day 1

Unit 3: Using Multiplication to Find Area
Lesson 3 of 12

Objective: Students will be able to deconstruct an array into two smaller arrays in order to find the total area.

Big Idea: Students need to practice deconstructing arrays with manipulatives in order to conceptualize the distributive property. This 3 day lesson takes the children through increasingly sophisticated activities to explore the "why" and "how" of this property.
