My boys are very mathematical. They are always doing activities with probability on their own. I read this book to come up with some more ideas for varied things that they could do. It is a well written book, threading a story of two kids into probability projects that kids can do on their own. I left this book on the library bookshelf and before I knew it, two of my sons were engaged in one of the projects.

Definitely for kids, my dear daughter, age 10, noticed it in the bag and read it and she is a hard one to find books that interest her. It has two main characters and is told in a story-line where events happen that are related to probability. The probability that mom will have a boy or a girl, the probability that a coin will land heads or tails, guessing candy in a jar, baseball batting statistics are all discussed without going so far into it that it's boring. I thought it was well written More...

Straight-forward, simple. One of the most successful "math lesson in a story" books I've read.
