Last night I came across a game called
" 8 Letters in Search of a Word"
in the internet. It's excellent - and can now be found at ...
http://www.wordsurfing.co.uk/43682.html
.... and then clicking on "Word Games".
Plenty of other interesting vocabulary games can be found on this page - and I'm continually looking to add new ones ......... so if you have any personal favourites that you'd like to recommend, please let me know.
In the meantime, have a go at " 8 letters" - and maybe suggest it to your students. The game was quite slow in loading first time - but is definitely worth the wait.
Best Wishes etc
