This custom Polygraph is designed to spark vocabulary-rich conversations about rigid transformations. Key vocabulary that may appear in student questions includes: slide, shift, translation, spin, turn, rotation, flip, mirror, or reflection.
After most students have played 2–3 games, consider taking a short break to discuss strategy, highlight effective questions, and encourage students to use increasingly precise academic language. Then ask them to play several more games, putting that precise language to work.
