Games for geometry 2.0.

The "geoplano" is a  didactic resource very interesting to work with geometry, it is useful to introduce the geometric concepts on a hands-on way.  

With it we can construct geometric forms, discover the properties of the polygons and, also, solve mathematical problems. All in all, it is a essential tool to learn maths.

It was created by Caleb Gattegno an mathematician Egiptian in 1960, who was looking for a method to teach geometry on a more didactic way. Although, nowadays most of them are done in plastic, the original one was a wood squared board with cloves which can be hooked with elastic rubber bands.

Here you can see and example of how you can do a "geoplano" by your own. It is really interesting and you also can see how to create the different forms.
