Math 7 (Class 53)
Lesson Title
Investigation 1: Variables and Coordinate Graphs
Overview
In today’s class students create a graph to represent how the number of daylight hours change as a function of the month. In addition, they write the final quiz focusing on operations with integers.
Textbook Sections
Problem 1.1 (Txt. p.5): Preparing for a Bicycle Tour
Vocabulary
coordinate graph
quadrant
axis
axes
x-axis
y-axis
coordinates
ordered pair
origin
vertical
horizontal
plot
scale
vertices
coordinate geometry

Key Attitudes
Willingness to work as a group to help meet individual and group goals.
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?
Key Knowledge
A table of values can be used to organize and analyze data.
A table of values, or a coordinate graph, need to be setup properly in order to be understood.
Key Skills
I can setup a coordinate graph: numbers (scale), unit names, variable names, title
I can collect and organize data for an experiment.
I can organize the data I collect using a properly labeled table.
I can plot data I have collected on a coordinate graph.
