Reading bedtime stories to children is a common strategy to boost kids' literacy--but what about doing the same for math? Parents hoping to prevent math anxiety in their children may find Bedtime Math to be a formidable ally. This resource offers more than two thousand short math puzzles designed as fun activities for parents to do with their kids at bedtime. New puzzles are added daily and each features "a cool fun fact, followed by math riddles at different levels so everyone can jump in." Parents can subscribe for free to get new daily Bedtime Math puzzles via email or they can download a free app (available for iOS and Android devices) where they can access the puzzles in both English and Spanish. Bedtime Math also offers the "Crazy 8s Math Club!" a kit of free resources designed to be used for fun after-school recreational math clubs. Bedtime Math was created by Laura Overdeck, a mom with degrees in astrophysics and public policy who loved playing with numbers as a child. Bedtime Math's activities have been used in studies by the University of Chicago and Johns Hopkins University, who both found their offerings to be beneficial.
