Murderous Math X 10 Books Slip Paperback – Import, 4 August 2011

Llego algo maltratado, pero aún así se disfrutaron

Some of the concepts may be hard to understand for a 10 year old but the stories are told in such a way that they are quite engaging, even without full grasp of the math concepts.

Very funny. Best educational book that my kid can read all day long.

My son is now 9, and has enjoyed these immensely. He's re-reading them now

My kids are LOVING this series. What a great addition to our unschool/homeschool library! We also bought horrible science, horrible history and horrible history. One of the best purchases I’ve made with our curriculum budget!
