GeoGebra Workshop

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
• 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
• Look at other activities and resources
online. Wiki middle school level contains
protractor practice
• Adapt Sketchpad activities for GeoGebra
• Write new explorations to match your
curriculum and standards and export as
java applets for your students to use on
your website.
