Define, evaluate, and compare functions. Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output. (Function notation is not required in Grade 8.)

The goal of this task is to give students a context to investigate large numbers and measurements. Students need to fluently convert units with very large numbers in order to successfully complete ...
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 ...
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...
