This book is great. I was able to pick the lesson's i wanted teach. I used this for a homeschool coop group,with Children ages k-4th grade. The books were easy to cut out and assemble. The kids loved being able to go home with their own book. The parents liked having there books to help them to review with their kids. We just did the planets, it was nice to be able to choose which ones you wanted. The reason I gave this a 4 star instead of a 5 is the books take some practice to photocopy, and the instructions for the books and study guides is very hard to understand. But I figured it out just took some practice. I will be using atoms and molecules next year hoping for the same success
