• Geometric Constructions

• http://www.mathsnet.net/articles/gsp4.html MathsNet: Review of Geometer's Sketchpad 4

• http://www.keypress.com/catalog/products/software/Prod_GSPModules.html The Geometer's Sketchpad Add-on Curriculum Modules (each module comes with a cd containing sketches) Available in Version 4:
1. Exploring Algebra with The Geometer's Sketchpad
2. Exploring Calculus with The Geometer's Sketchpad
Math & Science Education Center has a copy that can be checked out.
3. Exploring Conic Sections with The Geometer's Sketchpad
I have a copy.
4. 101 Project Ideas, Learning Guide, Reference Manual, and the cd of the software.
I have a copy. The license says that we may "Use or install the Software on the personal computers of faculty as long as the Software is used solely for preparation for instruction." Sketchpad 4 will be installed on the server this summer.
5. Other books that are listed on the website are being modified for version 4.
• http://www.xahlee.org/PageTwo_dir/MathPrograms_dir/mathPrograms.html#Content This is a list of math related programs. Most programs listed are shareware or freeware.

• http://aleph0.clarku.edu/~djoyce/java/elements/toc.html The complete text of Euclid's Elements Books I - XIII with interactive java Geometry Applets and commentary.

• http://home.a-city.de/walter.fendt/me/sphertriangle.htm The sum of the angles in a spherical triangle.

The following are Sketchpad 3 activities. With slight modifications, they can still be used in Sketchpad 4. As far as I can tell from searching, because the software is so new, there are very few resources (except for those mentioned above) that make full use of Sketchpad 4.
