Magnetic MightyMind®, It's the ONLY play alone activity toy that TEACHES KIDS as young as 3, HOW to SOLVE & BUILD PUZZLES. It provides the foundation they absolutely need to solve challenges and problems logically. MightyMind is based on B.F. Skinner’s connected system of learning that he developed at Harvard. It runs on a linked chain of connected numbered puzzles, focused on 2 goals. The 1st is to make it extremely easy for a child to solve a simple puzzle. The 2nd is to entice a child to pursue increasing challenges. The first puzzle, #1 is followed by variations of the puzzle that the child had just completed. The 2nd, 3rd, 4th, etc. puzzles make a child feel successful, confident and motivated to go on, attempting more puzzles that become increasingly complex. It’s a time proven system making kids smarter worldwide since 1978. When a 3- or 4-year-old reaches the 30th puzzle, a child will have gained enough skill to solve puzzles that many adults would have to ponder.
