    If you want an easy way to introduce Translation, Reflection, and Rotation, I highly recommend this DVD. Real-life events are depicted so easily. For example, one teen went down a slide and the Coordinate Plane was placed on the screen with a point on her ear to demonstrate translation (or slide). Even my students thought it was really cool! This DVD was so helpful. Thank you DCMP!!
