Oddly enough, my oldest son loved grammar. In fact, it was one of his favorite subjects. We used Rod and Staff to lay the foundation. It was a thorough program, but not always easy to finish in a year. The Easy Grammar Ultimate Series: 180 Daily Teaching Lessons seemed like a good substitute. We examined the grade 11 text. After a couple of lessons, Kingman complained that, "Nothing is clear. You have to make assumptions." I think coming from a curriculum that explains each concept in depth to one with succinct explanations may have been a big jump. Upon closer examination, I discovered that concepts are explained well enough. They are straight to the point with 1-4 practice questions. This program was created to get you through what you need to know about grammar quickly.
If you are familiar with Daily Grams, you will probably have an idea of how this works. In fact, the writers of the curriculum suggest using the text as a review book. I would agree. If you are finished with grammar study in your homeschool, but want to keep those grammar skills fresh as your juniors and seniors prepare for Accuplacer or CLEP exams, The Easy Grammar Ultimate Series: 180 Daily Teaching Lessons is a great review guide.
If you just want to review a specific aspect of grammar, the table of contents breaks it all down. For example, under the lesson on colons there are exercises on use with a bibliography, divided, words, lists, ratios and more. So you can zero in and be specific.
Another great way to use this guide would be through oral activities. We used to do it all the time with Rod & Staff because there were just so many exercises. To get through them, we would do half orally. The Easy Grammar Ultimate Series makes it easy as each lesson should only last 10 minutes. Everyone has 10 minutes to review grammar orally.
Because the text is laid out in such an organized fashion, it makes it easy to jump around. But the author suggests moving in sequence. It all depends upon how you plan to use the guide. If you are a fan of Daily Grams, then I think you'll like this. But I would suggest combining it with another grammar curriculum to round out a complete language arts program. The Easy Grammar Ultimate Series is a part of complete homeschool curriculum for 11th graders. For more information, click here.
