Geogebra is a graphics software application, this enables a teacher to create lessons and resources which can be used for teaching-learning.  It is a free educational application and and has its own respository of files, <nowiki>http://Geogebratube.org</nowiki>, available as Open Educational Resources.  It can be downloaded freely (from <nowiki>http://sourceforge.net/projects/Geogebra</nowiki>) and it is available on GNU/Linux and Windows platrforms.

Geogebra allows you to make sketches on a graphic view and the algebra pane describes the co-ordinates of the construction.  Functions can also be defined using the input bar.  It is possible to animate constructions in Geogebra by defining the variable as a slider. Geogebra also allows instruction to be typed in Indic languages.  The graphics view of Geogebra can be viewed in 2 dimensions or 3 dimensions.  The tool also has a spreadsheet option to work with list values for plotting a function.

Geogebra with it possibilities for visualization and animation can help support the building of these competencies.  The precision possible in drawing supports building the procedural fluency of geometric constructions, helping students understand why a particular step is necessary.  Teachers can use Geogebra to set up investigative questions for students to explore.
