What is GeoGebra?
GeoGebra is a set of free interactive maths tools used by over 100 million students and teachers. Its Calculator Suite brings graphing, geometry, 3D and scientific calculators together, so you can plot functions, build geometric constructions, explore surfaces in three dimensions and work through fractions or statistics in one place.
Teachers use GeoGebra Classroom to share activities and watch student progress in real time, and there is a large library of ready-made resources made by the community. GeoGebra Notes combines notes with live graphs and slides, and the Math Solver shows step-by-step working and practice problems. The tools run in the browser and as apps on phones, tablets and computers.
