2. Learning music can help children do better at math. Gordon Shaw of the University of California, Irvine, and Frances Rauscher at the University of Wisconsin compared three groups of second-graders: 26 received piano instruction plus practice with a math videogame, 29 received extra English lessons plus the game, and 28 got n special lessons. After four months the piano kids scored 15 to 41 percent higher on a test of ratios and fractions than the other participants.
