Grammar Rules!: For Students, Parents, & Teachers : A Straightforward Approach to Basic English Grammar and Writing Skills .I am so happy to have found this book. It makes grammar fun and easy. The lessons are short yet through, goal oriented and child friendly. The parts of speech are covered well and there is frequent review.My only compliant is that the answer key is bound in the book. I would prefer setting it aside. Overall it is a very strong option for grammar.
