I bought this book for my daughter for summer review. We used the Easy Grammar 4-6 book a couple years ago when I realized she wasn't learning grammar at school. I really liked all of the explainations in that book & thought this one would be the same way. It's just a book of daily activites to review what you should have learned prior to this. After doing a few of them you can easily tell what your child needs to review. We have been going back to the other book for review & then picking back up with the daily activites in this one.
I am using Daily Grams as a supplement to my Learning Language Arts through Literature with my 7th grader. It is a quick, easy-to-grade grammar/sentence structure boost. There are enough for every school day, and I like it because it keeps these skills sharp without being overbearing.
