Interlocking geometric shapes - squares

The Interlocking geometric shapes - squares consists of a rectangular frame, with 'soft' rounded corners, which contains three slots and their three squares, hand-painted in red, graduated from large to small. The slots are fitted with a knob to facilitate gripping and manipulation. Being able to look at and touch the shapes stimulates the tactile-muscular sense and helps the memory and the eye to perceive shape and size. The special grip of the knob encourages the right finger movement, useful for starting to write. The game allows self-correction, stimulates the exercise of motor skills; finding the right position for each piece encourages the development of attention and concentration.
