Rotation

__Title__: Rotation transformation

__Description__: Students will learn how to rotate a shape by given a center of rotation and an angle of rotation.

__Duration__: A 43- minute lesson

__Learning Objectives__: Students will be able to: · Rotate a shape when given a center of rotation and an angle of rotation by using GSP or Papers. · Understand the properties of rotation transformation

__Materials__: Rulers, grid paper, pencils, Impact Math text books, and Protractors.

__Step by Step Procedure__:
 * 1) Do Now ( A quick review about transformation)
 * 2) Use interactive motion to show student what a rotation looks like. Then summarize a few important critiques that need to given in order to make a rotation.
 * 3) Let students use the GSP to explore and create rotation transformation. (For students who are not comfortable with the GSP, they can do their work on grid papers.)
 * 4) Summarize the important properties of the rotation.

__Grade Level(s)__: 8th grade

__Support Materials__: Computers that are able to get online

__Related Standards__:

Students describe and identify transfoerformance rmations in the plane, using proper function notation (rotations, reflections, translations, and dilations.) Students draw the image of a figure under rotations of 90 and 180 degrees.
