Files from SHSU 2005 at Huntsville

Note: These files are mostly Geometer’s Sketchpad files. Some trial and error might be needed to figure out exactly how to use the files for presentations. Your best bet is, when prompted, to save the file to your computer, then execute it through GSP 4.0+. Not all of these files have been updated, so check back for cleaned-up versions periodically.
