Games and mathematical creativity with Tangram

What are we going to do in the workshop?

Tangram is a Chinese game known to many of us. But its vast reach may not be as explored.
After building our own Tangram, we will see how to explore this game in a novel and fun way.
We will carry out varied and original activities around the Tangram, some blind and others in groups.
We will explore shapes and geometry, but also combinatorics, proportionality and areas.
And all this, of course, with your hands!
We will adapt the activities to the ages of the participants.
