I got an early start this morning and posted Power Point .pptx slide shows for each of my 6 youtube video animations—the 3 basic rigid motions ones and the 3 Pythagorean Theorem ones. I put them in Animations so interested people could download the slide shows in pptx form and modify to their hearts’ content. If you want to use any of them for teaching, you could make some changes in Power Point: un-select the “Use Timings” box if it’s selected, and for a lot of the animations, change the Animations Options from “Start: After Previous” to “Start: On Click”. This will enable you to “drive” the presentation yourself, advancing the slides and animations to suit the pacing of your lesson with your students. Of course, it will also enable you to change things to suit your own aesthetic sensibilities. Go crazy.
