GeoGebra is the next Web 2.0 tool I chose to explore. GeoGebra is an online algebra, geometry, spreadsheet and graphing tool. GeoGebra provides dynamic and interactive tools which can make mathematics tangible to the students.

In an educational context, GeoGebra could be used to help students interact with mathematical content which would otherwise only exist on paper. GeoGebra also helps represents mathematical concepts in a different medium than would be typically seen in a classroom setting targeting multiple means of representation. GeoGebra can also be used to create mathematics lessons which can be created applying the UDL principle of multiple means of engagement. Finally, GeoGebra could be used in mathematics assignments to create graphs or logos instead of a traditional mathematics assignment addressing the UDL principle of multiple means of action and engagement. An example is the image for this page.

GeoGebra can help remove barriers for students who come from poorer areas. As the software is free, and recently developed an exam version, GeoGebra could remove the need for expensive calculators. GeoGebra can also help visual learners.

You need to be 13 years old to use GeoGebra.
