Books like Go Figure!: A Totally Cool Book about Numbers

This is, hands down, the most interesting book about math I have ever seen. In fact, I can guarantee I would have liked math a whole lot more growing up had this book been around when I was drowning in the concepts presented. I purposefully haven't showed it to Maddie yet because I wanted to check it out first—but she is at the age where math is still puzzles and magic and fun, so I plan to buy this and hope it stays that way for her.
