Here are five worksheets on the homophones two, too, and to, which I am confident you have noticed that are frequently confused–sometimes to hilarious effect (i.e. Dumb and Dumber To), but more often just, well, confusing effect.
If you find typos in these documents, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
