Pi (without the “e”) is the Greek letter (π) used in mathematics to represent the relationship of a circle’s edge to its diameter. Join us for an irrational celebration on 3/14 as we party and play with circles and shapes and puzzles and games! Get lost in loops, beautify with rubber bands, spin up a spirograph, and more! Included with Discovery Center admission. Sponsored by Dr. Zak Pediatric Dentistry, Huntington Learning Center and the Illinois Arts Council Agency.
