Science Vocabulary Readers Set: Human Body - 36 Nonfiction Books for Kids to Build Vocabulary (6 Copies Each of Eyes & Ears, Nose & Mouth, Skin & Bones) - Perfect for Classroom Learning & Homeschooling

I ordered this box of books for my child's 6 bday (science theme) for the goody bags. I was able to save 1 complete set for my daughter, and gave everyone else 1 of these books each. My daughter said they also have some of these in her Kindergarten, so she was excited about them. It's not overly complicated, but it's educational and not overly simple either. I'd say perfect for the K-2nd grade age groups.
