GSP files to accompany "Dynamic Representations and Flexible Trigonometric Thinking"
Note: If you do not have GSP installed on your computer, a demo version of GSP version 5 can be dowloaded for free so that you may open the files: http://go.keycurriculum.com/sketchpad_trial.html.
If the files do not open immediately on a computer with GSP installed, you may need to right click on the appropriate file above and select "save as." Then, start GSP and use it to open the saved file from the location you saved it on your computer.
