Math 7 (Class 99)
Lesson Title
Investigation 5: Using a Graphing Calculator
Overview
In today’s class we continue to learn how our GDC’s can help us make tables of values as well as learn more about what these tables of values can tell us about equations and what equations can tell us about tables of values.

Enduring Understandings
Change is fundamental to understanding functions.
Mathematical relationships can be represented in 4 main ways: Graphical, Numerical, Algebraic, Verbal (written and oral).
Essential Question
How can change be described mathematically?
How are patterns of change related to the behavior of functions?
How do mathematical models/representations shape our understanding of mathematics?
How are the ideas of rate of change, ratio, and slope related to each other?
How can I use a graphing calculator to make graphs?
Key Knowledge
A graphing calculator (GDC) can be used to quickly and accurately make a graph of an equation.
In order to make a graph on a graphing calculator (GDC) the equation must first be in “y=” form.
Key Skills
I can enter an equation properly in a GDC.
I can adjust the window on a GDC in order to view specific areas of a graph.
I can use GDC to explore equationss.
I can determine a y-value when given an x-value when I know the equation relating x and y.
I can create a table of x and y values when given an equation.
I can identify similarities and differences between two tables of values and can explain how these differences are related to the equations for these tables.
I can write an equation for a table of values which has a constant rate of change.
