Take a word or phrase and see how many TL words can be made out of it. May take a little bit of cajoling, but makes students think outisde the box and use their knowledge of the TL, not just the words they know on that topic.
Could give rewards for longest word, most useful word, unique words, most words found.
Could set a specific time limit with music.
Nice starter activity, especially for higher level (KS4+) students who generally have a larger vocabulary.
I’m sure this could be expanded more…
