What is GeoGebra?

GeoGebra is a free dynamic mathematics software package used by teachers of mathematics in classrooms across the world.  It joins geometry, algebra, tables, graphing, statistics and calculus in one easy-to-use package. It has won several educational software awards across the globe.

Why do maths teachers and students use GeoGebra?

In its simplest use, GeoGebra allows students to “see” what they are doing with their maths. For example when doing something abstract such as solving a pair of simultaneous equations – it is quick and easy to graph both equations so that students can visualise what the solutions to the equations mean. GeoGebra may be used to give students the opportunity to establish relationships in maths for themselves – for example the fact that a tangent to a circle is always at right angles to the radius at the point of contact. The dynamic nature of GeoGebra makes it easy for students to see how changes in one quantity affect other quantities. For example, when learning about standard deviation or correlation coefficient students can change one item in the data and see what effect this has on each quantity.
