Unit 5:

Quadratic Functions

How are parabolas used in the real world?
4 weeks

Students build on their experience with linear and exponential relationships as they investigate quadratic functions. They compare quadratic functions to linear and exponential functions and identify relationships in which the quadratic function is the most appropriate model. Continuing their work with domain and range, students graph quadratic functions and identify key features of the graphs. This includes understanding how different algebraic forms of quadratic functions can be used to identify key features of the graph, such as the roots, the vertex, and whether the function has a maximum or a minimum.

Essential Questions:

  • How are parabolas used in the real world?
  • How can we find connections between multiple representations?
  • How can we generalize from specific cases to general rules?

Unit Outline

8 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.
