Make homework fun with some tunes and a little creativity. After your kid finishes a subject, let her pick one of her favorite songs for a dance break, suggests Kathy Gorman, R.D., clinical dietitian and program coordinator at the Nutrition and Fitness for Life Program at Boston Medical Center. “It’s great if parents can actually do it with kids because it gets them so much more engaged,” she says. “Take turns doing different dance moves and copying each other. Make it silly and fun.” A five-minute dancing break will not only get your youngster’s heart pumping, but it will also boost her brain. Researchers at the Georgia Prevention Institute at Georgia Health Sciences University in Augusta found that overweight children who began to exercise regularly improved their ability to think, plan and even do math.
