Define, evaluate, and compare functions. Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.

This lesson relies on students’ understanding of constant rate, a skill developed in previous grade levels and
reviewed in Module 4 (6.RP.A.3b, 7.RP.A.2). Students are confronted with the fact tha...
In this lesson, students continue their investigation of time and distance data for a falling object and learn that the scenario can be expressed by a formula. Students are introduced to the terms ...
In this lesson, constant rate is revisited as it applies to the concept of linear functions and proportionality in
general.
This lesson introduces students to the fact that not all rates are continuous. That is, we can write a cost function for the cost of a book, yet we cannot realistically find the cost of 3.6 books. ...
This lesson is when students begin graphing functions of two variables. Students graph linear and non-linear
functions and the guiding question of the lesson, “Why not just look at graphs of equat...
In this lesson, students investigate the rate of change of functions and conclude that the rate of change for linear functions is the slope of the graph. In other words, this lesson solidifies the ...
With the knowledge that the graph of a linear function is a straight line, students begin to compare properties
of two functions that are expressed in different ways in this lesson. One example of...
In this lesson, students work with simple non-linear functions of area and volume and their graphs.
