- online repository for .ggb files
- 1 click upload
- 11000+ materials uploaded
4.0 the current stable version
4.2 including CAS
(Planned release in September 2012)
4.2 beta - CAS
Python window
5.0 beta - 3D
Automatic Theorem Proving
GeoGebraWeb
Kinect, wii, Raspberry Pi, etc.
What is working:
- All commands, including the new ones from GeoGebra 4.2
- Algebra View
- Toolbar
- Input Bar
- Style Bar
Bonus features that the Java version doesn’t have:
- Save and share your .ggb files to Google Drive
- Edit -> Insert Image from -> Webcam
- Equation editing in the Algebra View
We hope to soon start work on adding:

Free software is a matter of liberty, not price.
To understand the concept, you should think
of free as in free speech, not as in free beer.

go together.
International GeoGebra Institute
Core Aims of IGI
Towards a GeoGebra Institute network
- Teacher training and support
- Offer workshops & support
- Material and software development
- Share free materials
- Research
- Encourage and coordinate collaborative research
- (Outreach)
- Enable disadvantaged communities
- Rather than country-wide institutes, GI network serves better a country’s needs
- Establishing local institutes, but encourage a coordinating committee (locally decided)
- Individual application followed by a network application
Institute network case: Spain
World Wide User Community
Difficulties of serving large communities
Planned Institute Centres
100 Current GeoGebra Institutes in 70 countries.
More coming soon …
- GIs can reach mostly local teachers/communities
- Members work in different institutions
- Large geographical areas to cover
- If many people involved that results too large staff
- Maintain independence of work
- Linz, Austria – Software development
- Budapest, Hungary – Community support
- Cambridge, UK – STEM and Research
