Here are some great websites to help you become better typists. Typing is such an important skill, so have a go! Do some lessons first at typingclub.com, then try some games at the keyboarding games page.
www.typingclub.com This one is simple and really easy to use - I just had a go. It is very straightforward.
www.learninggamesforkids.com/keyboarding_games.html This one has heaps of different games on it. We loved qwerty warriors - a bit addictive :) You might find one that suits you here too. Maybe once you have had a go at some of the practice ones in the typing club you could have a game on this site.
