Magnetic MightyMind is just like the original (1978) MightyMind®, but its magnetic so the design tiles are easier to manipulate and its perfect for travel. Its the only toy activity in the world that teaches kids how to build and solve puzzles. It was created way back in 1978 based on the research and work of the Harvard behaviorist, B.F. Skinner. Its an intricate linear program comprised of 30 steps (puzzles), arranged in a numerical sequence thats disguised as a play activity. Kids get glued to it, because it generates a feeling of success and it builds a childs confidence and self-esteem. The proof of this is apparent when you realize that almost every purchase is generated as a result of one parent or grandparent telling another. It starts off simple enough for a 3 year old and within just 30 steps a child develops enough skills to be able to complete a 64 piece jigsaw.
