Points in the Coordinate Plane

Activity Overview

In this activity, students will use the Cabri™ Jr. Application to explore the coordinate system.

Before the Activity

Install the Cabri Jr. App on the students' graphing calculators using TI Connect™, a TI Connectivity cable and the unit-to-unit link cables

See the attached PDF file for detailed instructions for this activity

Print pages 55 - 62 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Show the coordinate axes, and create a point in the first quadrant

Display the coordinates of the point

Drag the point to all four quadrants and observe changes in the coordinates

Construct lines through the point perpendicular to the axes

Hide the perpendiculars and measure the length of the point from the x-axis and the y-axis

Drag the point to all four quadrants and observe the changes in the measured distance

After the Activity

Students will fill in the Data Collection and Analysis sheet.

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
