Unit 3: Systems of Equations
Lesson 5 of 13

Objective: Students will be able to model with systems of equation from a more advanced perspective. The equations take on a more realistic context and the focus is on the meaning of the resulting system. Students will be able to use the model of their system to show the benefits and limitations of different cell phone plans.

Big Idea: Students love to send text messages and some have to pay for their own cell phones. This lesson turns the tables and puts the students in the position of pitching cell phone plans to consumers. They use their knowledge of systems of equations to make gra
