Lesson Plan--Quadratics--Lesson 8--Quadratic Inequalities

Lesson Plan: Quadratic Inequalities

In this eighth lesson of the Quadratic Functions and Equations Unit, students will learn how to solve and graph quadratic inequalities. Quadratic inequalities extend the concepts of quadratic equations and help students analyze solution sets using number lines and coordinate planes.

Students will:

  • Understand the difference between quadratic equations and quadratic inequalities
  • Learn to solve quadratic inequalities algebraically
  • Graph solution sets on a number line and in the coordinate plane
  • Interpret the meaning of the solution in real-world contexts
  • Apply test points to verify solution regions

Designed for Algebra 1 and Algebra 2 students, this lesson aligns with Common Core standards and strengthens students' ability to analyze inequalities involving quadratic functions. Understanding quadratic inequalities is essential for advanced problem-solving in algebra and calculus.

This is the eighth lesson in a ten-part unit on quadratic functions and equations. Upcoming lessons will focus on further applications of quadratics and advanced function analysis.
