Dr. Chheda – A series of books that helped my kids get through middle school is The Big Fat Notebook. And they have a book for every subject. But I think it really helped my kids understand some of those concepts that maybe they weren’t quite getting when the teacher explained it. And in the book, it’s very colorful it’s very short, but I find that it was very easy to understand. Not only for my kids but to help me remember that topic and then tutor my kids on it. So I am in no way affiliated with this publisher or with this book, but just to be helpful, this series really helped my kids in middle school. Maybe it might help your kids.
