For teachers looking for some good spelling games and sites, Richard Byrne of Free Technology for Teachers has a great list of 5 sites for you. I use Spelling City with my own children and would highly recommend it to anyone. I have not used the other sites he lists, but I am sure they are good. I plan to have my own children test some of them this summer. My daughter really likes to spell things and play spelling games, so we will see which one she likes best. Currently, she loves Spelling City. Give some of the sites listed a look and test them out and see which one might work for your own students.
