Unit 6:

Quadratic Equations

Solving quadratic equations in one variable
5 weeks

In this unit, students use algebra to solve quadratic equations in one variable. This includes factoring quadratic expressions as well as using the quadratic formula and completing the square to solve quadratic equations. Students should make connections between different methods of solving a quadratic equation to inform their solution pathway. Students will also build on their earlier work with linear systems by using algebra and graphing to solve systems consisting of a linear equation and a quadratic equation in two variables.

Essential Questions:

  • How do we measure change?
  • What does a solution represent?
  • How do we determine the best method for obtaining a solution?

Unit Outline

9 Components

Every unit begins with an Initial Task and ends with a Balanced Assessment, both focusing on core mathematics of the unit. The core mathematics is developed through a series of resources around Big Ideas; as you move through the unit, keep students focused on how these ideas are connected and how they address mathematical problem solving. Before attempting the Balanced Assessment, students have an opportunity to synthesize their knowledge through a multi-day Formative Assessment Lesson and teacher-designed re-engagement lessons.
