Geogebra It is a free application for teach and learn algebra in which you can find interactive graphics and applications to practice mathematics. Although the application, for what I have used it, has more utility in secondary, high school and university, it can also be applied in primary. Thus, in the image that illustrates the article you can see an example that I found in the database of shared resources, for teach to add fractions. In this case the fractions cannot be added because they do not have the same denominator.
The application of Geogebra has generated around a community of very active teachers and students in which they share learning materials that are free and free, for example, they have even a YouTube-like channel they call GeoGebraTube. I think it's a great application to learn and work with a subject like very abstract algebra. From the little that I have used it seems to me that it requires a work discipline to get acquainted with her although once done the power is very high. From my student experience I think it is a tool that combines scientific calculators and advanced programming options, such as Matlab, to develop complex models.
Although mathematics is complex and requires work, capacity for abstraction and spatial vision, this application may help to make things a little simpler, with visual and very practical examples. In any case, the merit will always be that of the teacher who, taking advantage of the tools at his disposal, is able to explain and reason the student.
Geogebra It can be installed on mobile devices and on the browser desktop. Works on Java and it is free software that ensures that it incorporates improvements by the development community although that requires the user to be aware of the new features that are added.
The founder and Director of Geogebra is Markus Hohenwarter He works at the Johannes Kepler University Linz in Austria. Markus began working at Geogebra in 2001. Among the developer community there are, or have been, Spanish and among the users of the application there are also teachers from Spain sharing resources. In IneveryCrea, for example, I have found many useful experiences also for primary school.
