PHOENIX -- There could be something new to do with your kids at bedtime.
Most parents read a bed time story, but a New Jersey couple decided to try something different. Laura Overdeck and her husband are into math.
"A few years ago with our two older kids, we started doing a math problem every night," said Overdeck.
"Pretty soon, our third child, when he turned 2, started yelling that he wanted one also. That's when we realized that we were on to something."
A month ago, they started the non-profit Bedtime Math, which could help you do math problems with your kids.
"We send out an e-mail (with math problems) every night," said Overdeck. "I write the problem during the day."
Overdeck said it's too early to tell whether Bedtime Math will help to improve children's math scores.
"We really are thinking of finding a group at a university to start studying this, so that in a year or two, we can see what impact it's had," said Overdeck.
