Lesson topic: Solving inequalities

## Instructor Materials

• Teacher guide
• Slides
• Practice Problems resource
• CCRS standard: 7.EE.4b
• Learning goal: Compare and contrast (orally) solutions to equations and solutions to inequalities. Draw and label a graph on the number line that represents all the solutions to an inequality. Generalize (orally) that you can solve an inequality of the form px + q > r or px + q < r by solving the equation px + q = r and then testing a value to determine the direction of the inequality in the solution.
