GeoGebra introduction for teachers 

The following videos introduce different aspects of GeoGebra. They are meant for newcomers not knowing GeoGebra on beforehand.

GeoGebra is a freeware, non-profit program for teaching math to students, especially in the age group 12-20. You can install GeoGebra from http://www.geogebra.org/cms/download . GeoGebra is widely spread across the world, and it is translated into more than 60 languages. Present (Oct2014) version 5.0 includes CAS and 3D-drawings.

You can find thousands of videos about GeoGebra, se YuoTube or http://www.geogebratube.org/ . I here try to cover important aspects from the syllabuses in 17 videos with video 1 as the very first introduction.

Comments (especially if I use some math terms incorrectly in English) etc. to Frede Dybkjær, mail frede@dybkjaer.com .

If you represent many teachers, then you can have a CD sent by letter containing all of this.
