Tangram

The Tangram is a Chinese very ancient game, which consists in forming silhouettes of figures with the seven pieces given without putting them on top of each other. The 7 pieces, called "Tans", are: 5 triangles of different shape, a square and a parallelogram or rhomboid shape. From these figures, the students have to form different shapes. This game is currently used both as a hobby and as a support in the classroom.

With this resource, students can work management and knowledge of the mathematical elements, such as for example, the different types of geometric elements. In addition, we also put into practice reasoning processes for the resolution of problems.

The level of difficulty of this activity can vary. For younger students, you will be given templates where students may see the shapes of the geometric figures that they should use to make the image, while older, teacher can give students only the image so that they have to guess how it is formed. An example of this we can see in the following images:
