Required Materials

In addition to the general requirements for participating in Math Teacher Link, this module also has the following requirement:

• The Geometer's Sketchpad application (version 4 or higher) needs to be installed on the computer you will use.
  Go to the Geometer's Sketchpad home page of Key Curriculum Press, the makers of the software. This page has information, resources and support for The Geometer's Sketchpad software. Follow their information and pricing link to order the current version of Geometer's Sketchpad software for either your Mac or Windows machine ($69.95 - single user). Install the program on your machine according to the instructions that come with the program.
• We have stayed with Geometer's Sketchpad rather than go with GeoGebra because we find that using well supported and well documented software saves valuable time and aligns well with other published materials.  It is the same reason we use Word rather than OpenOffice for our word processing.
