The Art of Problem Solving is probably the best math related website on the Internet. If you have never spent time on this site it has some amazing content for competitive mathematics. My two favorite things on the site are 1) Alcumus which is a self paced, level based math curriculum teaching everything you need for Math Counts and 2) my personal favorite thing on the Internet right now For The Win (FTW) which is a game in which student can log on and compete with each other on Math Count like problems. Here is a link to the site, Alcumus, and For The Win. If you don’t have an account for Art of Problem Solving I would recommend you get one and start keeping track of what you are doing.
