Reason for Alignment: This lesson is quite similar to the Cartesian Coordinate System lesson and can be used interchangably. It contains discussions and teacher directions included to guide students through the concepts. The level is appropriate for this stage of a student skill. The discussion in the lesson should be useful for working with students in understanding the four quadrants and examples.

Reason for Alignment: The Graphing and the Coordinate Plane lesson is a good beginning look at coordinate graphing. It covers the basics, which should be review, and vocabulary. Students should appreciate the review from Book 1. All four quadrants are used and explained.

Student Prerequisites

Arithmetic: Student must be able to:

perform integer and fractional arithmetic.

Technological: Students must be able to:

perform basic mouse manipulations such as point, click and drag.

use a browser for experimenting with the activities.

Algebraic: Students must be able to:

work with very simple linear algebraic expressions.

A unique ordered pair of numbers that identifies a point on the coordinate plane. The first number in the ordered pair identifies the position with regard to the x-axis while the second number identifies the position on the y-axis

Lesson Outline

Focus and Review

Remind students what has been learned in previous lessons that will be pertinent to this lesson
and/or have them begin to think about the words and ideas of this lesson.

Objectives

Let the students know what it is they will be doing and learning today. Say something like this:

Today, class, we are going to learn about graphing lines on the coordinate plane.

We are going to use the computers to do this but please do not turn your computers on until I
ask you to. I want to show you a little about this activity first.

Teacher Input

Lead a
discussion on the number line and the coordinate plane.

Guided Practice

Practice the students' point plotting skills by having them play the
Coordinates! Game The game allows users to figure out and to practice using the coordinate plane for giving the
"address" or exact location of particular points.

Independent Practice

Have the students practice their graphing skills on
graph paper using the tables of values they generated in the lessons on
Functions and
Linear Functions

Have the students test their skills by playing the
Maze Game

Closure

You may wish to bring the class back together for a discussion of the findings. Once the
students have been allowed to share what they found, summarize the results of the lesson.

Alternate Outline

This lesson can be rearranged in several ways:

Omit one or the other of the computer activities to reduce the amount of time spent.

Add a discussion about fractional movement on the coordinate plane

For students who aren't ready to handle negative numbers yet, replace the Coordinates activity
with the positive numbers only alternate versions:

Introduce students to the next lesson by using
Simple Plot to plot the tables of points that the students generated.

Suggested Follow-Up

After these discussions and activities, students will be have learned to plot points on the
coordinate plane and to read the coordinates off of a graph. The next lesson
Graphs and Functions will introduce students to the graphical representation of functions.
