This illustrates and allows students to play with the Properties of Algebra which can be selectively turned on to show specific properties and examples or used as a review. I have included a worksheet and a key (numbers will vary) my website www.toolsformath.pbworks.com under the GeoGebra link. I noted that division by zero resulted in a result of infinity rather than undefined on this application. You may need to address that to your students. I wrote this to adapt notes to interactive examples; however, it could be expanded to include geometric examples of the different properties.
