Time Out says
At the Museum of Math, numbers, shapes and patterns take on fun properties rarely seen in your average classroom. Birthday party themes like Multi-Morphing Megaplex let your kids construct shapes big enough to walk through, while GeoGlow has guests using light sticks and geometry to create a glow-in-the-dark polyhedra. Every party includes full-day admission to the museum, a private room for 90 minutes and a birthday cake, with special add-ons available, such as fun goody bags and personalized treats. Ages 3 and up.
