dynamic mathematics software for all levels of education that joins arithmetic, geometry, algebra and calculus. It offers multiple representations of objects in its graphics, algebra, and spreadsheet views that are all dynamically linked. While other interactive software (e.g. Cabri Geometry, Geometer's Sketchpad) focus on dynamic manipulations of geometrical objects, the idea behind GeoGebra is to connect geometric, algebraic, and numeric representations in an interactive way. You can do constructions with points, vectors, lines, conic sections as well as functions and change them dynamically afterwards. Furthermore, GeoGebra allows you to directly enter and manipulate equations and coordinates. Thus you can easily plot functions, work with sliders to investigate parameters, find symbolic derivatives, and use powerful commands like Root or Sequence.

award winning software that joins arithmetic, geometry, algebra and calculus.

Here is the list of Winners and losers from Jane Hart's list. Some new entries: Google+ (debuting the highest at 26), Ted Talks (at 30), and for math teachers - Geogebra.

This open source mathematics software includes graphics, algebra, and spreadsheet capabilities and is increasing in use. This is one of those "must loads" on your school or university websites.
