I had several parents ask me if I knew of some math applications that they could download onto their phone. I found this: http://www.wired.com/geekdad/2009/04/5-basic-math-apps-for-the-iphone-and-your-kids/. Here you will find five math applications that allow your child to practice basic math skills. They can be found on itunes and are reasonably priced. Try them out and let me know what you think of them!
