I really like this book. It's pretty simple and straightforward. For my son that has limited concentration and patience for desk work, these are small manageable chunks that he can do and be done for the day, but that still teach what he needs to know.
This grammar curriculum is just right! I am using it with a rising 4th grader and a 2nd grader. It is simple but effective. It really drills the grammar rules into the child in a easy but not boring way. I recommend this program to anyone looking for a gentle first grammar introduction.
I have used an "all inclusive" language program before I purchased Easy Grammar for my kids. They like it because it breaks grammar into bite size pieces and is easy to follow. Also, it is easy for me to administer because I can have them do roughly one page per day. I then do separate spelling and writing curriculum. This seems to be pretty basic for second grade, but we have just started.
I used Easy Grammer through out my two daughters homeschool experience. They loved the fact that they could work on their own most of the time and when testing came at the end of each year they always did very well in the grammer section. I know this is from their time using Easy Grammer. They are both in college now, but they still talk about Easy Grammer being one of their favorite school books.
