This document outlines a lesson plan for teaching students how to solve one-step inequalities. It involves students working through 21 practice problems in pairs, discussing each step of the solving process with their partner. For each problem, students are instructed to discuss the inverse operation needed to solve the inequality, have one partner solve and the other graph the inequality, and check their work with each other. The lesson emphasizes using inverse operations to isolate the variable and determining whether the inequality symbol needs to be reversed when graphing.
