Great Books Math Dinosaur Complete Set

This is the Math Dinosaur complete set, designed to teach math concepts in an easy and fun way, tailored to children's level. It consists of various stories and illustrations, allowing children to learn math with interest. It will make a great gift for children taking their first steps into math. My child didn't like them much, so the books are practically brand new. The supplements also show no signs of use. I am including 10 volumes of "Happy Sex Education" as well.
