We bought this for our twin fifth graders, but the whole family enjoyed using it. The "editor" format is a much more interesting way to learn grammar than a traditional textbook. There are exactly five errors in each paragraph. We make finding all of them a contest. The paragraphs are interesting and the errors are varied. The units are bite-sized, so one doesn't get overwhelmed (we do three per day.). The answers are clearly written. The price is a good value. The content well above avegate. We highly recommend.
