GeoGebra WorkshopGCCTM Meeting

Dr. Joanne Goodell

Cleveland State University

September 13, 2010


What is geogebra

What is GeoGebra

  • A free dynamic mathematics software for schools that joins geometry, algebra and calculus

  • Two windows, one for graphics and the other for algebraic expressions form the interface

  • Drawing pad used like Geometer’s Sketchpad, can be used without the algebra window

  • Can create interactive Java applets from your drawings that can be run from any web site

  • Book has great introductory materials

  • Wiki has lots of free materials

  • Could be used to supplement or replace GSP


Geogebra options

GeoGebra Options

  • Can run as independent Java applet from the computer you are using-this may not work in the lab without tech support setting it up.

  • Web start runs the Java applet from within the browser installed on the computer you are using-will probably work without tech support, but you must have internet access.

Further exploration

Further Exploration

  • Look at other activities and resources online. Wiki middle school level contains protractor practice
