This Evaluating Solutions of One Step Equations and Inequalities lesson plan also includes:
Review the differences among equations, expressions, and inequalities. Demonstrate with a scale how an equation balances out on both sides, and how an inequality has a set of solutions. Present a few real-world problems for your mathematicians to solve in pairs. Close by creating a game of word problems and then playing it as a class. This lesson was intended to teach your class the process of solving equations and inequalities by the substitution method.
