Title: Systems of Equations: What Method Do You Prefer?
Description: The purpose of this lesson is to help students apply math concepts of solving systems of equations to real life situations. The students will use the three methods of graphing, substitution, and elimination to solve the system of equations.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Supply and Demand
In this lesson, students write and solve a system of linear equations in a real-world setting. Students should be familiar with finding linear equations from 2 points or from the slope and y-intercept. Graphing calculators are not necessary for this activity, but could be used to extend the ideas found on the second activity sheet.
