This jigsaw puzzle uses a "small steps" method to develop concentration and work skills, leading to learning while playing. Starting with puzzles with fewer pieces and gradually increasing the number of pieces, children can improve their concentration and work skills while experiencing the sense of accomplishment from completing the puzzle. The pieces are sized to be easy for even toddlers with unfamiliar fine motor skills to handle, and a special thickness is used so that they can be played with repeatedly. The pieces are interlocking (the same type as a real jigsaw puzzle) so they fit together easily and are less likely to come loose once fitted. You can progress through four stages, from 2 pieces to 6 pieces.
