With a little paper, glue, and other household items, you can make math jump off the page and into the real word with this title.  It covers an expansive range of facts and theorems, each with explanations, craft projects, puzzles, factual tidbits, real world connections, and glossaries.  While they make a good attempt of explaining some very complicated subject matter, much of it would still benefit with some adult supervision and may be beyond many in it’s age range, i.e. Hyerbolic Paraboloids for instance. All in all though, the book does an excellent job of pairing  math with kid friendly experiments and real world comparisons.  An excellent teacher resource for those children who utter, “When will I ever use this?” . Includes instructions and website access to print the activities if needed.
