I am using this with my 2 boys who are in 5th and 7th grade. It is a great review for the 7th grader and plenty of new information for my 5th grader. We are working through 1 lesson a day since they are older though. The boys love the format and so do I. It is very simple to use.
This book is an all-inclusive volume that covers dictation, narration, basic grammar and writing. It can't get any easier - read the script and follow directions to teach the concepts. The teacher's guide is very thorough and the student workbook is very helpful too. It is a little stark, but that is just fine for an older student. We began our homeschool grammar program using Shurley English which was good, but I like that this program requires fewer books and includes the dictation and narration exercises.
