Unit 2:

Linear and Exponential Functions

How do we measure change?
4 weeks

This unit continues the work started in the first unit in Algebra I, but adds a narrowed focus on linear and exponential functions. Students investigate the rate of change and the initial value as key features that define functions. For the first time, students write equations that describe the relationship between quantities for linear and exponential functions.  Whereas in Unit 1 much of the work is descriptive and general, Unit 2 asks students to calculate, quantify, and formalize their analysis and comparisons of functions.

Essential Questions:

  • How do we measure change?
  • How do we quantify the differences between representations?
  • How do we quantify the relationships between quantities?

Unit Outline

7 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.
