Files from GCTM 2004 at Rock Eagle
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.
