Check out the full episode on how I scaffold Geometric Transformations.
Summary of the Episode
Scaffolding geometric transformations can be extremely beneficial if you have students who are currently struggling with on-grade level math.
1. Identifying Each Transformation
Start off with students identifying which transformations are which. I use these “slang” terms to help students better understand the academic vocabulary.
Translation – Slide
Reflection – Flip
Rotation – Turn
Dilation – Large and Tiny
2. Translations
Start off with a single point on a 1 quadrant graph, doing a single movement. Add two movements, 4 quadrant graphs, then shapes. Create the algebraic rule by looking at the coordinates.
Activities for Translations
3. Reflections
Practice identifying reflections over the x-axis versus the y-axis. Use mirrors, tracing paper, and counting spaces from the line of reflection.
Activities for Reflections
4. Rotations
Do not be like me and wait four years before using tracing paper when teaching rotations. It is a life saver and makes teaching them so much easier.
