Unit 4:

Linear Equations and Inequalities in Two Variables

How can we define and solve relationships between two quantities?
4 weeks

Students build on Unit 3 content to create, interpret, and graph systems of equations and inequalities. Students will continue to describe how variables are related within a given situation, and will create two related function rules that each model a distinct relationship in the situation. Graphs, tables of values, and function rules are each used to determine the solution set of a system of equations or inequalities. Students will compare different solution methods to strategically choose which method best conveys a system’s solution set. 

Essential Questions:

  • How can we apply our knowledge to model real-world situations?
  • How can we represent and analyze our solutions to problems?
  • How can we represent the same thing in multiple different ways?

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.
