**Geogebra/ICT**

GeoGebra is a free mathematics software package which is used by teachers of mathematics in classrooms across the world. GeoGebra can be used to enhance student learning by providing students with a dynamic view of key mathematics principles. While its benefits in teaching geometry is clear from the start, it is also really useful in teaching of trigonometry, probability, statistics, number, algebra and functions.

You can find lots of useful videos and manuals on how to use GeoGebra in a classroom below.

## Geogebra Videos
