The Geometric shapes puzzles - square, circle, triangle consists of a rectangular birch frame, with "soft" rounded corners, on which the three basic geometric shapes are carved. The joint makes it possible to insert: a circle, a square and an equilateral triangle in wood, in the corresponding reference frame. The three shapes are equipped with a knob to facilitate manipulation and the right finger movement for starting to write. Being able to observe and touch the shapes and the relative outline stimulates the tactile-muscular sense and helps the eye to perceive the shapes. Playing allows self-correction, finding the right position encourages the development of attention and concentration.
Sensory Material 0-3: made up of a set of objects "grouped according to a specific physical quality" - weight, temperature, size, shape, color, sound, etc. - the improvement of the perception of each sense favors exploration and knowledge. From about 12 months up to 3 years. The frame and the shapes are in birchwood, hand-painted in red (square), blue (circle), yellow (triangle) with Luxens water-based paints with reduced environmental impact, certified "Ecolabel". The knobs are in beechwood. The game is useful for starting the study of geometry.
