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