This lesson teaches students how to solve algebraic inequalities and graph them on the number line. They solve inequalities with addition, subtraction, multiplication and division, and with negative and positive numbers. When multiplying or dividing with a negative number, they learn to reverse the sign. Students choose an open or closed circle to move to the number line, and then choose a right or left arrow to move next to their circle and size it to fit their graph. Fun, interactive lesson.
