For english I made a variation like this. Bring a bag of letter tiles from Scrabble to class and pick one letter out (or have a student do it)and show it to the students. The first one must say a word with that letter, the second one also but the third one says a word with the next letter of the alphabet and then go back to the original letter two times and then again the next letter.
Example: Let's say the letter is A: First student says Apple, the next Airplane, the next Bus, the next Air, the next All, the next bicycle.... and so on.
Note: Don't bring alcohol to class, PLEASE!!!!
Well, hope it works for you and if not, you also have there a game to play with your co-workers after class.:)
