Worksheets for a Talk
I have organized many of my worksheets into various workbooks. Most of these you can locate at http://tube.geogebra.org/dochopatsbu. I have a few worksheets I have created specifically for presentations about GeoGebra. My presentations, typically with working links, are available by following the link in the list of presentations at https://sites.google.com/site/drhopkinsbackground/ .
