I've always found rotations to be a difficult concept to teach. This discovery allows students to examine rotations that have already been made in order to develop the rules for rotating. Answers included. When you print copies for students, make sure that they get a copy of the image page with the coordinate grid. It would be helpful to give this to them un-stapled to the discovery so they don't have to flip back and forth.

This can be used as an in class discovery or could be given as homework to be used with a 'flipped classroom' approach where students would come to class with exposure to rotations.
