Divide the class in two or three teams, or make students play individually (it may result more difficult).
Make each team write a sentence using only five words. All the words have to begin with the letter that the teacher decides. Proper names are allowed only once in each sentence. A more difficult version would consist of making sentences with five or more words.
The team that writes a correct sentence first wins a point. The team that gets to five points wins the game.
