There's number fun waiting everywhere--it just takes a math detective, armed with these really cool, colorfully illustrated activities, to find it. Budding mathematicians can start the search by going on a cereal count and estimating how many pieces are in the bowl; staying on the lookout for shapes; or even becoming a "human clock." Measure your family and find out who has the smallest head or the biggest fist. Find lucky pennies with your birth year on them, play calculator or dice games, and keep a tally of all the things that happen in your house. Surprise your friends by proving that it is possible to walk right through a piece of paper. Ratios and measurements, probability, units of time and distance, powers of two, and simple geometry have never been so entertaining.
