The Geometer's Sketchpad

It is a software program that has revolutionized the teaching and study of geometry. Originally designed for use in secondary classrooms, SketchpadTM is so versatile that today is recommended for students from grade 5 through college.  It has evolved into a tool with far broader applications than it was intended for.  As a dynamic exploration tool, SketchpadTM  can be used to explore algebra, trigonometry, calculus, art and science.  It allows for dynamic explorations in geometry so that students can see the changes in the figures as they manipulate them.
