Programme to teach kids to touch type?

[Lovage]

Can anyone recommend a programme to teach kids to touch type? I learnt from a very boring but effective programme on a VAX machine about 20 years ago, but I imagine there are more exciting ones out there now designed for kids. DS1 is 9 and DS2 is 6 but the 9 yr old is the one I want it for most. Both understand that it's' the kind of thing you have to keep practising to get good at.

BBC Dance Mat is good fun.

Mavis Deacon is pretty good. There are various games to help you practice and get your speed up.

Thanks. BBC Dance mat looks particularly fun. Can you go on to the next level whenever you like or only when you have got sufficiently proficient at the current level? DS1 is the kind of child who always wants to rush on and it would be useful if the programme put the brakes on...

Any other recommendations?
