You've all heard of hangman right? Yes, of course you have! Well, instead of hangman with one word, how about hangman involving a passage instead:
Students have a maximum of 50 wrong guesses (keep count on the board). They get to guess one word around the class; if it's correct, it's written in, if not it's put by the side of the passage and they lose one of their 50 lives.
Help can be 'bought' by the student; for example, a letter in every word in exchange for one of their wrong guesses.
Students should be given as much time as they need to talk about the sentence structure and the grammar of the passage. This exercise makes students aware of how sentences are constructed, and the punctuation also helps with, for example, linking devices.
