Kids and adults will see how varied peoples developed systems to problem solve in their daily life: the farmer's need to know how far he needs to walk to bring water to his crop (measuring distance) or how many days he has until the weather changes (the calendar); the trader's need to know how to barter and measure worth (symbols, place value, calculations); the tax collector's need to find a way to insure that his taxes are properly paid (tallying and tally sticks, half of which was called the "stock"); observations of nature and a need to imitate and learn (patterns, shapes, symmetry, tessellations, geometry, computer binary code). Kids can make an abacus (Chinese), tally sticks (British), a quipu (Inca), read hieroglyphics, write on papyrus, measure distance and time Olympic-style, and more.
