Instructor Overview

Students represent problem situations using expressions and then evaluate the expressions for the given values of the variables.

Key Concepts

An algebraic expression can be written to represent a problem situation.

To evaluate an algebraic expression, a specific value for each variable is substituted in the expression, and then all the calculations are completed using the order of operations to get a single value.

Goals and Learning Objectives

  • Develop fluency in writing expressions to represent situations and in evaluating the expressions for given values.
