Lesson 16

Find the Value of Expressions

Lesson Purpose

The purpose of this lesson is for students to find the value of addition and subtraction expressions in a way that makes sense to them.

Lesson Narrative

In previous lessons, students interpreted expressions and connected expressions to story problems and drawings. This is the first lesson where students begin by working with only expressions. Because students have matched expressions to drawings in previous lessons, students may create a drawing to find the value of the expression. Students may also use their fingers or objects to represent the expression and count to find the total or difference.
