The site Bedtime Math Problems is a new concept that is making national news. This makes adding math skills to the traditional bedtime reading routine a very easy task! Problems are broken into three ability levels; Wee Ones, Little Kids, and Big Kids. Answers are included with each problem.
There is a link on the upper right side of the Bedtime Math homepage that allows you to subscribe to a problem of the day as an email list-serve. This could be a great resource for parents to use to improve math dialogue and mathematical sense.
