The geoplane, a fantastic resource to practise geometry!

It is a fantastic resource to learn maths in a manipulative way!!!
The geoplane was created by Caleb Gattegno in 1960, who looked for a method to teach geometry in a more didactic way. Currently the most of the geoplanes are made of plastic but the origina one consists of an  wood square board with nails that towered out and you could hook elastic bands that were used to represent different geometric figures.

There are three types of geoplane:
1. ORTHOMETRIC: 
A cuadricular weave of 25points the most of the times.

2. CIRCULAR:
A colection of points of a circunference that have the same distance of space. It lets making regular polygons of 3, 4, 5, 6, 8, 12 and 24 sides. The last one is the most frequent.


3. ISOMETRIC:
A triangular weave. The points are located in the vertexs of the equilateral triangles.



So, to conclude, you can teach this manipulative resources not just to create figures, you can also teach it to study the propierties of an circunference for instance or to solve problems. I think that it is really interesting and it is a way to learn differently.

Here you have some video that show how you can create a geoplane in different ways, I hope you like them!!
