I teach at an urban school where academics typically aren't high on the priority list of most of my students. Using problems from this book, my students enjoy learning Math. I'll post a random problem and left it up to see who can guess it. There have been some interesting guesses before they get to the correct one, but it interesting to see how they come up with their solutions. It definitely makes them think. Worth getting if you are looking for a book to get your students interested in Math.
