The user interface of GeoGebra is flexible and can be adapted to the needs of
your students. If you want to use GeoGebra in early middle school, you might
want to work with a blank sheet in the Graphics View and geometry tools. Later
on, you might want to introduce the coordinate system using a grid to facilitate
working with integer coordinates. In high school, you might want to use algebraic
input in order to guide your students through algebra on into calculus.
