数学を革新的に学ぶ・教える

GeoGebra is an interactive mathematics platform for teaching and learning. It provides calculators and learning apps, ready-made educational resources, tools for creating materials, and features for interactive classroom lessons. GeoGebra is used by teachers and students at school and university.

You can use GeoGebra to perform calculations, graph functions, solve equations, create dynamic geometric constructions, explore 3D mathematics, and work with data and statistics. You can also use ready-made learning resources, create your own materials, and share interactive activities with students. During a GeoGebra lesson, teachers can follow students’ progress and provide support.

GeoGebra is primarily designed for mathematics teachers and students, from school through university. Teachers can use it to explain concepts and create interactive learning activities. Students can explore mathematics visually, practice their skills, and test their ideas.

GeoGebra’s calculators, apps, and educational resources are free for non-commercial use. This includes most use by teachers, students, and parents at school, university, or home. Commercial use requires a separate license. If you are unsure whether your intended use is commercial, please contact the GeoGebra partnerships team.

For most teachers and students, we recommend the GeoGebraスイート. It combines our main mathematics tools in one app and works across different devices and platforms. If you need an app with a more limited set of tools or want to create advanced GeoGebra resources, visit our downloads page to compare the available options.

No. You can use many GeoGebra features without an account. For example, you can create constructions and visualizations, solve exercises, browse resources, and save files locally on your device. You need an account if you want to save your work online, access it from different devices, or use GeoGebra’s online sharing features. You can create an account using an existing Google or Microsoft account.

Yes. Once you have downloaded and installed a GeoGebra app, you can use its main mathematics tools without an internet connection. You will still need an internet connection to search for online resources, sign in to your GeoGebra account, or save and share work online. You can save your work locally on your device while offline.

You can find instructions, tutorials, and answers to common questions in the GeoGebra Help Center. If you cannot find the answer you need, you can ask the GeoGebra community for help and exchange tips with other users.
