Solving Systems of Equations by Graphing vs. Substitution - Partner Activity! Partner A solves by graphing while Partner B solves the same system by subsitution. They should get the same answer, it not, they work together to correct any mistakes. This works GREAT!
Use this PowerPoint presentation and note-taking outline to introduce solving and graphing inequalities. It has layered animations to allow you to question students as you present and only contains four slides due to the animation involved. The note-taking outlines coordinate with the PowerPoint presentation and include eight additional examples as follow-up. The outline can easily be incorporated into an interactive notebook.

Systems of Equations sorting activity: identify types of systems of equations (with 1 solution, no solution and infinite solutions) when data is presented in tables, graphs, sets of coordinate pairs and pairs of equations.
This is an exciting lesson for middle school math students in which they learn to translate between algebraic expressions written in word form to algebraic expressions written with mathematical symbols. The theme of the lesson is World War II and the role the Navajo Indians played in the war effort. Students train to become better translators and increase in rank from "Private", to "Colonel", and lastly to "General".
