Problem solving requires patience as well as creativity. Puzzles tend to be about finding different solutions to issues. They require children to think about their choices and find the right pieces as with puzzles, there aren't any shortcuts. They cannot cheat if a piece doesn't fit. They learn how to correct themselves, and if the piece doesn't fit into an area, they have to stop and figure out where that particular piece should fit. The act of manipulating each piece, turning it around and checking the fit is an excellent exercise in problem solving.
