Lesson Plan: Evaluating Algebraic Expressions Mathematics • First Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to evaluate simple algebraic expressions with one or multiple variables and how to apply this in real-world problems.
Objectives
Students will be able to
- find the numerical value of an algebraic expression
- by substituting the individual variables for numerical values,
- by substituting multiple variables given as a simple expression, such as ,
- use the numerical value of an algebraic expression to draw conclusions about real-world systems.
Prerequisites
Students should already be familiar with
- writing algebraic expressions,
- relating algebraic expressions to real-world systems,
- order of operations.
Exclusions
Students will not cover
- substitutions that require algebraic manipulation,
- substations that require a variable to be expressed in terms of another variable,
- algebraic expressions with more than 3 variables,
- simplifying algebraic expressions,
- rearranging algebraic equations to find the value of a variable.
