A book to bridge grades.

This book is really balanced and explains the subject matter in such a simple way. I got the Grade 6 book for my daughter before she moved to fifth grade. She has been working on this book during the summers and loves it. I have been helping her out as some of the lessons are new for her, but so far she has had no problems understanding. The explanations are simple enough for children to read on their own. I think it will really help her in grade 6. It has a nice mix of topics and activities and is not monotonous. I think this book does a great job as a bridge between grades.
