Seventeen fun, Web-based educational games are on Funbrain.com's Numbers site. The games cover basic arithmetic, fractions, graphs, algebra, and many other topics. Math Baseball is the most popular game on the site, which awards singles, doubles, or triples depending on the difficulty of the question. All of the games have varying levels of difficulty, ranging from easy to "Super Brain." There is even an activity where the user spells the words of a number written on a check (but you might want to hide this one until your child gets a little older). Sections for parents and teachers are also on the site; so, there are plenty of resources for everyone.
