Rotations in the Plane - Cabri Jr: Interactive

Activity Overview

In this activity, you will explore the invariant properties of rotations and the results of rotations in the coordinate plane.

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 Cable

Use the TI-Navigator™ to transfer the attached Cabri Jr. AppVar files to each calculator

See the attached PDF file for detailed instructions for this activity

Print pages 53 - 56 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Use the AppVar to go directly to the exploration section

Construct a triangle to rotate and a point that will be the center of rotation

Construct a rotation angle tool

Rotate the triangle using the tool

Drag the sides and vertices of the triangle and points on the tool and observe the relationships between the pre-image and the image

Construct a triangle on a coordinate axis to rotate

Rotate the triangle and identify the coordinates of some vertices

Form a counter-clockwise rotation, drag the vertice and look for patterns in the coordinates of the vertice and its image

After the Activity

Review student results:

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

Re-teach concepts as necessary
