Squares and triangles puzzles

The squares and triangles puzzles is a game consisting of a rectangular birch base frame, with 'soft' rounded corners, which contains three grooves in which three yellow squares are placed: one whole, one divided into two parts, one divided into four. By manipulating the joints, the child first sensitively learns the shape of the puzzle and then its names: the parts of the square as a whole and its first divisible parts. From an early age, the child 'absorbs' the shape and becomes able to recognize it in the surrounding reality. Trial and error in order to find the right position for the interlocking parts of the square help with problem-solving and exercise eye-hand coordination.
