Personally, I think "Geometer's Sketchpad" is widely used in mathematics teaching. Geometer's Sketchpad is a designated software for junior and senior high school students in China. It is suitable for teaching platforms such as vector analysis, drawing and function drawing of mathematics, plane geometry and physics, and can dynamically show the position relationship and operation change law of geometric objects for teachers and students. The operation of the geometric sketchpad is relatively simple. For a teacher who is familiar with the operation, it only takes 5- 10 minutes to make a geometry courseware with moderate difficulty. Official website, Geometer's Sketchpad, provides free download address, rich tutorials and courseware templates. Supersketchpad is a multifunctional educational tool software specially designed for basic education, knowledge and intelligence in China. Compared with the geometric sketchpad, the function of the super sketchpad is inevitably lengthened. Supersketchpad is mainly used in plane geometry, algebraic operation, analytic geometry, function image, probability statistics, solid geometry, algorithm programming and other fields. , suitable for beginners and basic education.
