Geometric rotations with a hole punch
Difficulty: Easy Geometric rotations can be awkward to teach, but here’s a way to teach them visually and hands-on. What you need: • a hole punch • scissors • templates (printed from scaffoldedmath.com) That’s it! Students will be able to see geometric rotations 90 degrees clockwise, 90 degrees counterclockwise and 180 degrees. They can then analyze the coordinates to prove the rotation rules.
