This is a complete smartboard lesson covering how to solve and graph 1-step inequalities. The warm-up is a subtracting integers pyramid. Click blue triangle along the bottom to reveal the numbers to subtract. Work your way to the top. The essential question and objective are clearly stated. Define inequality and note how it differs from an equation on a number line. Work through examples together - all included, just pull them in (blue dots on the side). Justification for each step is included. Click to reveal definitions or steps. Closure to the lesson is a tic tac toe game. Answers to the questions are located behind the WOOSH.
