Blue wooden joints

The game of wooden joints is entirely made of birch, it is useful for the education of the eye to the shapes. It is composed of five square tiles, with "soft" rounded corners, which serve as a basic frame to contain different geometric shapes: a square, an equilateral triangle, a pentagon, a trapezoid, a rectangle. All the shapes are equipped with a knob to facilitate the manipulation and the right movement of the fingers useful for starting the writing. Being able to observe and touch the shapes and the relative shape stimulates the tactile-muscular sense and helps the eye in the perception of the shapes. The game allows self-correction, finding the right position favors the development of attention and concentration and eye-manual coordination.
