Whether it’s measuring, graphing or estimating, “Fun, 2, 3, 4: all about a number of things!” will help visitors apply math to everyday activities while having fun.

 The exhibition consists of 16 hands-on exhibits designed to encourage family and group interaction.

 At the "How Many is a Million?" exhibit, visitors can converse about large numbers as they try to reach a million turns of the wheel and break the goblet inside the exhibit. The "Double Your Allowance" exhibit allows visitors to see and feel exponential growth by lifting up tubes containing one penny, two pennies, four pennies, up to 2,048 pennies.

Visitors can measure a model of a dinosaur using their own feet as units of measurement.

Ms. Measurooni uses graphs to show how visitors' height, weight, and grip strength compare with other people. At the "Super Bowl" exhibit, visitors can make histograms charting how well they do at rolling a tennis ball down a lane to the center of a backboard; patterns of light appear where the balls hit. Visitors also can count like the Aztecs, or team up with a partner and take the time challenge.
