Working with Point Rotations in the Coordinate Plane
Activity Overview
Using Cabri Jr. and the properties of rotations to get a true understanding of how a figure is rotated about a point.
Before the Activity
1. Make sure that the students have an understanding of rotations. This lesson will provide a more precise understanding of point rotation, a topic that some students have a difficult time with. They will use the basic rotation properties to explore the properties of point rotation.
2. Load the appvar ?ROTPT? onto the student?s calculator.
During the Activity
See attachment file for activity list. Through this process, the student will explore rotations about a point, how the figure is rotated a certain amount of degrees, and how the distnace holds between the point of rotation to the figure.
After the Activity
Review student answers:
