I am a big fan of dynamic geometry. Whether it be Geometer's Sketchpad, Geogebra or Desmos. So I always appreciate when someone helps students work with any one of those tools. I also have a series of videos that walk you through some constructions. If you don't know a construction is when you build a geometric item that always keeps its properties (like a square). That is when you drag any of the points, it may change size or orientation but not loose the properties of that geometric figure. You can see those here
