This activity is meant to be introduced after students have become generally fluent in solving one- and two-step equations.
The notes include explanations about switching the inequality when multiplying or dividing by a negative coefficient.
The practice includes solving, graphing, and checking.
The partner activity is meant to save space and be an automatic answer key for your students: Partners have a different set of 10 questions each, but the answers should be the same. If they produce different answers, they must check each other's work to find and fix the mistake.
