Introduction to Geometer's Sketchpad

The lessons are an introduction to use of Geometers Sketchpad (GSP). Each of the lessons is a construction of a geometric figure. The lessons include voice and subtitles describing how the construction is made. We suggest you use the pause bar as frequently as needed. Once you have understood the lesson try these sketches yourself, thinking about why the sketches work. You may want to consult the tutorial that accompanies GSP. 



This website was designed specifically for the Reconceptualizing Mathematics textbook, published by W. H. Freeman & Company, but it is available for use by any prospective or practicing teacher of K-8 mathematics.
