Index of GeoGebra Interactives
Here we provide links to over 30 GeoGebra interactives embedded into this text. This list is offered as a quick reference, and to allow access to our GeoGebra code. These interactives were formatted to be embedded into this text, and may look “funny” and lack clear directions when viewed outside of the text. We do not recommend that these interactives be used by students in stand-alone mode. Anyone should feel free to save and modify these interactives as they see fit.
