A creative way to learn by "cheating"

My grand niece, who is now 6 years old, enjoys playing the "cheating game". She asks for this game when she sees me. I gave her four plastic pieces and asked her to form any of the shapes shown on the card. For example she has to form the house shown as picture #17. It is difficult for her. Even an adult will not be able to form the shape. I told her that she is allowed to "cheat". She can turn the card over and see the solution which shows the four pieces separately. She enjoys the game better when she is allowed to "cheat". By "cheating", she learns how to solve problems. It is a fun way to learn.
