Well I have the perfect game for you.This will be the perfect thing for your Educational assistant. The site has 4 levels with 12 challenging stages to teach the kids to type.Now this is on BBC.com. I guarantee that everyone in your class will learn how to type efficiently in about 5 days.You do not have to pay on this sight just go to level 1 and start typing.On the first stage they will teach you the home keys and where to place your fingers.Once you pass a level you're going to get a certificate.In the end of each level there will be a song depending on what music genre is represented.The thing I like about this site is that it can teach you how to type without looking.I will put the link in my source(s).What are some good typing games for kids?

Sorry I don't know about free but I learned to type with Mavis Beacon... they have games in there where (ie) you have to type a word fast to make the penguin jump from iceberg to iceberg to escape the shark :p It's a cool program but not free sorry, you'll have to buy it :/
Mavis Beacon is a fairly popular series of typing games. I don't know if the games support online play. Although, I don't think kids with special needs need to be playing online anyway.
