Session 5: Linear Functions

In the previous session, you developed proportional reasoning skills by making absolute and relative comparisons, comparing ratios, making scale drawings, and looking at graphs of proportional relationships. In this session, we'll explore linear relationships by looking at lines and slopes. Note 1

In This Session:

Part A:

Linear Relationships in Patterns

Part B:


Part C:


Part D:

Putting It Together

Part E:

Thinking About Technology



We'll also use spreadsheets to aid us in our exploration. If you feel comfortable using a spreadsheet program, feel free to start the lesson now. If you've never used a spreadsheet before, or if you have but would like a review of the basics, click here for a short tutorial.

Learning Objectives

In this session, we'll use spreadsheets to explore dynamic dependence and linear relationships. We will:


Recognize linear relationships as they are expressed in tables, equations, and graphs


Understand that linearity is expressed in constant differences


Use spreadsheets to work with tables, equations, and graphs


Explore the role of slope and dependent and independent variables in graphs of linear relationships


Develop an understanding of rates and how they are related to slopes and equations
