They're, Their and There--You're and Yours--It's and Its. Here's a quick review quiz with ten short fill-in-the-blank sentences for each of these common word usage errors. You can instantly add 3 quiz grades to your grade book or grade it as a 30-item quiz. I've included a "retake" version with mostly different sentences. You can have students retake the sections they did poorly on, or have them redo the entire page and record the highest grade for each section. I've used this with both 5th graders and 7th graders. I was surprised at how competitively they viewed this assignment--almost all of them were comparing their scores with neighbors after I had them swap papers and grade this in class. I've also included a key for both the original quiz and the retake.
