Great book to keep in the classroom!!! It uses easy concepts to educate students about big numbers. I like how the author uses a funny example of building the tower of people to show that a million will pass the Moon. It is humorous and very easy to understand, my student love it.

Letter Format was interesting. The history of the time period was very informative-I wanted to learn more.
