GeoGebra

I have to say that I did not know this program until now thanks to the subject of didactics of geometry and that at first I did not think it was a very useful program, but after learning how the program basically works, I have seen the infinite possibilities that both To teachers as students.

This free program is becoming a revolutionary tool in teaching and learning math. GeoGebra allows us to make dynamic constructions, easily exportable to web applications, in which we can manipulate expressions (geometric, numerical, algebraic or tabular) and observe the nature of relations and mathematical properties from the variations produced by our own actions.

If we want to be good teachers we have to adapt to our students, who coexist with new technologies from a very young age, so they always tend to keep a positive relationship with technological devices which we have to take advantage of to make the most of both motivation Of students and make the most of them.

What I like most about this application is that it offers you several possibilities: you can use the application in an online way so you do not have to make any downloads which makes it very simple; You can download it on any computer, laptop or tablet, so if the centre has one of them it would be convenient to install it in all so that it is always available even if there is no internet; Last but not the least interesting, it can be installed on smart mobile phones, so you could abandon the idea that mobile is a problem in schools and move on to see mobiles as a tool that we should take advantage of, as they could always check what they are doing in a very fast way and clear their doubts in an autonomous way.

In addition to the free and easy learning, GeoGebra's most notable feature is the double perception of objects, since each object has two representations, one in Graphical View (Geometry) and another in Algebraic View (Algebra). In this way, a permanent connection is established between the algebraic symbols and the geometric graphs.

Finally, comment that I would introduce this application in the second cycle of primary and that would teach several videos that clearly explain how to use the different tools. We would also be practicing all at once to practice what interests us to form their knowledge, but what would do more with this program would be to give them the freedom to experiment, make mistakes and learn themselves.
