Free App for Teachers
GeoGebra Graphing Calculator is a special app that has been designed to make it easy to learn and teach a wide range of different maths and science functions. Teachers are able to use the app to set special problems for their students, while tasks that have been completed by students can be instantly shared with their educators so that they can receive quick feedback to check that they are on the right track, although the format is dull to say the least.
