Wondering how to help your mini-mathlete avoid the dreaded summer brain drain? Check out bedtimemath.org. Started by Laura Bilodeau Overdeck—who has been adding a nightly math problem to her kids’ bedtime routine for years—the site provides daily word problems for kids to answer. The problems touch on real-life topics (like nutrition, holidays, even the Oscars), and each is modified for various age groups. “We have to use math in our everyday lives,” says Overdeck. “And we’re trying to get kids beyond the drilling and testing they’re used to in school—we’re trying to get them to see the fun side of math.” Bonus? The handy site is now available in app form (For iOS and Android, free).
