Using Geogebra

Geogebra is a mathematics software for learning and teaching.

You can download either a webstart version or an offline version at

Once geogebra is installed you can use geogebra files to learn about a particular topic, such as gradient of a line, vector addition, or 2-D matrix transformations.

Get on-line help, off-line help (as pdf files) or training videos here:

I will (gradually) upload my geogebra files to the geogebra wiki upload manager, here

Hint: Many other teachers (and students) have uploaded materials and they are usually more sophisticated than my own efforts.

Click on a *.ggb file to save it to your computer. Then open it with Geogebra and explore!
For example, download my "column vectors.ggb". Move the floating vectors to discover the laws of vector addition and subtraction.
