These Geogebra sketches are meant to serve as an introduction to the four Euclidean motions. (I am a proud supporter of the Glide Reflection.) Probably for middle school and above. If you try them out, I am always interested in feedback. The Motion Intro does not actually use a lot of the dynamic nature, but generated a lot of connections with my preservice teachers. The Motion Control led to a nice discussion of what information is needed for each motion, as well as how to find that information (like the center of rotation) for a given motion. The webpages have the questions that I asked my students.
