Fodor's Expert Review National Museum of Mathematics
There's no exact formula to get kids excited about math, but the sleek two-floor National Museum of Mathematics (MoMath)—the only cultural institution devoted to math in all of North America—comes close to finding the perfect fun-to-math ratio. Kids can ride square-wheel trikes, create human fractal trees, build virtual 3-D geometric shapes (which can be printed out on a 3-D printer for a fee), use lasers to explore cross sections of objects, solve dozens of puzzles, and generally bend their minds. The popular Robot Swarm exhibition allows kids to explore swarm robotics and interact with two dozen small (Roomba-like) glowing robots, using simple math rules. Exhibits are best suited to kids aged six and up, but preschoolers can still enjoy many interactive exhibits like the Math Square, a light-up floor programmed with math games, simulations, and patterns. The museum closes at 2:30 pm the first Wednesday of every month.
