Choose a grammar lesson from the St. Martin’s Handbook (it can be anything from Part Eight – Part Twelve) that you might struggle with. It might be fragments, run-on sentences, semicolons, etc.
Once you’ve chosen your lesson, then teach this lesson to the class in this discussion! The best way to learn something is to teach it, so here is your opportunity!
I would like this to come from your own wording, not simply copying from the textbook. You might add your own personal flare to it – be creative and have fun 🙂
