My children like paperwork for school. The Easy Grammar series is set up great for having them master a concept. I would like to say that the student workbook is just that, a workbook. The teachers edition has the student workbook pages, lesson ideas, and the answer key. If you want to copy pages or have student just work in teacher book you can and don't need to purchase the student workbook.
I don't care for the order that parts of speech are introduced. I also think that the page numbering system is confusing when trying to match up the teacher's guide with the student workbook. The teacher's guide is a lot more bulky than it needs to be because of how many pages are essentially blank with only one line of text on an entire page - ie. "PAGE 281=WORKBOOK PAGE 116." (There are at least 16 of those.) I would prefer a teacher's guide without reproducible student pages that is less bulky and less expensive with a student workbook that is separate rather than a teacher's guide that is almost 600 pages long and is awkward to use in making copies of student pages. Wouldn't buy again, and probably wouldn't even use again with a second child in a few years. Will keep searching for a grammar program that I like, because this is not it.
We were really struggling with grammar courses...right up until we got this book. Having to spend the front end time learning the forty words was a great way to begin. We made games, used the book, wrote poems, had contests, did "before and afters"...I took longer than normal on this end because of the kids' learning disabilities; I even made "Go Fish" cards and a "Concentration" game. They learned the words and so much of the rest became easy. The method works VERY WELL!
We used this curriculum last year and my daughter loved it. It is easy to teach and understand. She insisted we use it again for the 4th grade. She was so excited when it finally came in the mail. Be sure to get the daily grams. It really does help with retention.
