One can find information about Sketchpad on the Key Curriculum website. Sketchpad is software designed for Mathematics Teachers and Educators and gives students a clear way to learn and understand equations. Graphical representatives can be used and high school students can use geometric shapes. Sketchpad works with white board presentations and the website has a free twenty minute trial.

If you have the front and back covers of the sketchpad, you can use tape to fix the problem (especially duct tape). For actual sketchPADS (as opposed to sketchBOOKS), I'm guessing you could use a clamp or something, though that would interfere with flipping the pages. In case your sketchpad finally breaks, by the way, see if you can find a folder to hold the papers in. A cheap paper or plastic one should work fine.
The Sketchpad, developed by Ivan Sutherland in the early 1960s, was a revolutionary computer program that enabled users to interact with graphic elements on a screen using a light pen. It is considered one of the earliest graphical user interfaces and laid the foundation for modern computer graphics.
