Sketchpad is a dynamic construction and exploration tool that enables students to really understand mathematics in ways that are just not possible with traditional methods or with other programs. Portable 'Geometer Sketchpad 4.07' does not need installation. Just carry it in a flash drive and use on any computer, even without administrator access. No settings on the host computer are changed. The portable app creates a sandbox folder in its current location, where it stores all its settings and temporary files. Make as many copies of the app as you need. No more conflicts with other applications.
