GeoGebra is a free dynamic mathematics software tool for all levels of advanced education. The application combines geometry, algebra, spreadsheets, graphing, statistics and calculus and bundles them into one easy-to-use package.
Users can use GeoGebra as a standalone product or they can also take advantage of other features including interactive learning, teaching and evaluation resources that are available online.
GeoGebra is really for math experts and is a complex application aimed at users who are comfortable with difficult math, but it does have advantages over other applications in that GeoGebra provides multiple representations of objects that are all dynamically linked. Basically, the idea is to connect geometric, algebraic, and numeric representations in an interactive way. This can be accomplished with points, vectors, lines, and conic sections. With GeoGebra you can directly enter and manipulate equations and coordinates, thereby enabling you to plot functions; work with sliders to investigate parameters; find symbolic derivatives; and use commands such as Root or Sequence.
Key features include:
- Free to use software for learning, teaching and evaluation.
- Fully interactive, easy-to-use interface with many powerful features.
- Access to an ever-expanding pool of resources.
- A fun way to really see and experience mathematics and science.
- Available in many languages.
- Adaptable to any curriculum or project.
- Used by millions of people around the world.
Overall, GeoGebra is a great tool that spans numerous mathematical fields. It provides multiple representations of dynamically linked objects that cover arithmetic, geometry, algebra and calculus and there is vast online resource community to assist users. GeoGebra is a dynamic mathematics application that has received numerous educational software awards, and supports STEM education and innovations in teaching and learning globally.
