online games to teach language concepts?

[sphil]

I want to find a computer-based way (if possible) to teach DS1 simple adjectives: big/little; long/short; colours etc. Any ideas? He is very motivated by the computer, so it would be a built in reinforcer!
TIA

www.do2learn.com has some useful stuff for free, including this game for colours:-

for some adjectives

Thanks TC - will definitely try the pairs one, though we're not quite at the 'over/under' stage yet. Don't think the colour one will grab his attention as there's no sound. Useful website!
