Today in class students ignored me as I reviewed how to solve two step equations - which works for inequalities with the additional rule of turning around the inequality symbol when you multiply or divide with a negative number to find the solution set. I showed how to use the number line to graph and plug in possible solutions that make the inequality true. Students continued to ignore me as I demonstrated that the rule for turning around the inequality symbol does not have anything to do with adding or subtracting negatives in the inequality - ONLY multiplying and dividing.
