If you're still a bit shy about sharing ideas yourself (an outrageous suggestion, I know), here's another one, which I learned at some conference or other.
Vocabulary Circles
A bit like Hangman with a twist.
You draw a big circle on the board, and write the numbers 1-6, evenly spaced around the circumference.
You tell the class that you're going to write examples of, or words associated with the hidden word in the middle.
You then draw a little line for each letter of the word in the middle, just like Hangman.
Let's say that in the middle you've got: _ _ _ _ _
Then you write 'banana' against no 1, and wait for a guess.
If you don't get one, you write 'orange' against no 2, and hope that someone can spell 'fruit' (the word in the middle).
You write in 'fruit' … and then ask the class what word no 3 is, and no 4 and nos 7, 8, 9, etc, until they run out of fruit! (This is where you elicit which fruit they know - and which they'd like to know. Ever heard of 'cloudberry'? It's the English word for 'hjortron', which is very common in the north of Sweden, and which a Swedish class would like to say.)

I have a variant for the clever clogs, which goes 'sun', 'star', 'planet', 'time' … and then carries on to 'telegraph', 'newsweek', until someone gets 'newspaper' (Clark Kent worked on the Daily Planet, remember!).

In other words, not just a vocabulary exercise - could also be connected with cultural and societal aspects.
