A handy activity is here for you to help coach your writers on how to construct a complete sentence, how to correctly punctuate it, and what kinds of words should go in them. After a discussion, pupils are charged with writing a short story, exactly 12 sentences in length, that is about fishing. No periods, capital letters, question marks, or exclamation marks should appear. The story is given to a partner, who must correctly punctuate and capitalize where needed. A clever idea.
