Dilations- Lesson Bundle

Published on

In the "Dilations- Lesson Bundle", students will explore dilations and their properties. Throughout the lessons, students will be encouraged to make observations related to their investigations, leading them to discover the properties of dilated figures.

Reflections_and_Rotations

Reflections and Rotations

Updated on

Students will reflect figures over the x- and y-axes. By studying what happens to the coordinates of the pre-image and image points, they will write rules for reflecting points over the axes. Students will then rotate figures about the origin, in both clockwise and counterclockwise directions. Again, they will study what happens to the coordinates of the pre-image and image points to write rules for reflecting points 90° and 180° about the origin.
