Find numbers everywhere! Budding mathematicians can figure out how long the mails take, estimate how many pieces of cereal they need to fill a bowl, and unearth geometry lessons from their own bathroom tiles. Measure your family and find out who has the smallest head or the biggest fist. Turn yourself into a human ruler or a human clock. Find lucky pennies with your birth year on them, fold a newspaper until it's thicker than a phone book, and keep a tally of all the things that happen in your house. Surprise your friends with card tricks, guessing games, and calendar puzzles. Measurement, probability, time and distance, powers of two, and square roots have never been so much fun!
