We?ve written before about howusing yourhands can help your memory. Are your kids?or you?havingtrouble with math? Another reason to use your hands!

Psychologists have discovered that kids who are told togesture while doing math are more likely to solve mathproblems.

Some were told to gesture,others were told not to gesture, and some were not toldanything either way (they were the controls). These were allkids had made mistakes in solving math problems in the past.
