I can't recommend this book highly enough. My son learned about combinatorics, exponential notation and graph theory all from this book. It touches on so many fascinating concepts and kids - and adults- with many levels of math literacy can all appreciate it.

Thats great to hear. DS8 loves his "You Can Count on Monsters" Book which is on multiplication, factoring, and primes(which he first read around age 6). The library doesn't have the newer book and I've been too cheap to spend the money for it new. Your review is pushing me over the edge...
