Love this book. Yes, it's repetitive BUT this has helped my 3 older kids. The 2 older ones that couldn't get grammar now enjoy doing this book. I will use this with my 4th youngest child. I have used the workbook only and also the combo book which includes the teacher's portion which includes the answers.
I am very pleased with this book for Grammar. My son struggled some with English in school but now is understanding everything a lot clearer. I just wish it was sold in a set with the teachers book. But it is still a great buy.
I hoped I would love this program, but I really don't. I don't care for the order that parts of speech are introduced. If this were my daughter's first exposure to grammar, or if I was not as comfortable with teaching the subject, I don't think that this would have been a good initial introduction to the subject. As it is, since we've covered the parts of speech in the past, using it as a review is working.
We have used Easy Grammar's 2nd grade book through Easy Grammar Plus. I like the fact that the book is written for the student. The child can read the assignment and complete it independently in about 20 minutes. The consumable workbook is also very affordable. Although I purchased the teacher books with the answers, I don't need to reference them often. This curriculum has worked for our 5 school-aged children. I would highly recommend it.
