GEOBOARD was born from an idea inspired by the Egyptian mathematician, pedagogist and philosopher Caleb Gattegno, who in the 1950s popularized the homonymous technique of the geoboard, which consists in applying small pegs on wooden surfaces and subsequently intertwining a cord between the pegs to form flat geometric shapes, a technique created to give a manual approach to geometries. It is precisely by following the same concept of manual skill that the geometric shapes are then created, which are then shown on the tiles in the collection.
