Sixth Annual
NYC Math Festival

Saturday, August 20, 2022
10:00 am to 4:00 pm ET (New York)
Fosun Plaza, 28 Liberty St.
(in person)

Add a little math to your summer!  MoMath is pleased to present the NYC Math Festival on Saturday, August 20, from 10:00 am to 4:00 pm ET (New York), providing a full day of math fun in the sun for all ages.  Bring your friends and the entire family to Fosun Plaza at 28 Liberty St. and enjoy hands-on math exhibits, entertaining mathematical games, and intriguing puzzles and brainteasers.  Plus, take home a little bit of MoMath: we’ll be setting up an outpost of Additions, the shop at MoMath, for all your summer gift needs.

The event is free and open to the public.  No registration is needed.

Featured Festival Fun

MoMath 2 Go!
Slice shapes with lasers, explore giant mazes, crank up the math tunes, design a roller coaster, and more… Enjoy these and other Math Midway classics.  Plus, jump into an exciting race of mathematical and visual perception with Play Truchet and enjoy the mind-bending puzzles of Twist-n-Roll.



MoMath’s Iconic Number Line
Guests of all ages can enjoy a 120-foot-long trip along MoMath’s iconic number line!

As he tosses clubs and balls in crowd-thrilling arcs, educator John Chase demonstrates how mathematics is the secret to a juggler’s ability to anticipate the path of a ball or club in space and time.



Mathematical mimes Tim and Tanya Chartier create the illusion of a wall, play catch with an invisible ball, and pull on a nonexistent rope in a series of fun vignettes illustrating concepts including estimation, tiling, and infinity.


Julia Robinson Mathematics Festival
Join us for some magical math moments!  Experience the joy of a play-based approach to problem solving and critical thinking and build confidence through challenges you conquer while surrounded by a supportive community.


The Lab for the Developing Mind at New York University (directed by Dr. Moira Dillon) investigates the origins and development of those incredible cognitive abilities that make us human.  Primary among them is our uniquely human capacity for mathematics!  The lab has been collaborating with MoMath on research and outreach since 2017.  The following activities will be presented by the lab:

Multiplication City is a fun way for kids to exercise multiplication rules.  Kids roll two dice and multiply the numbers rolled, then grab that number of pieces of colored paper blocks and stick them as windows onto buildings on a poster board, creating many buildings and a city skyline in the end.  If they have trouble with the initial multiplication problem, then they can discover the answer through the process of putting the windows on the buildings.  We have found a way to make this game portable (using large fold-out boards).  It’s a hit with kids at different ages, especially because we live in NYC, where skylines are so prominent!

Speed Sorting is a fast-paced game exercising approximate numerical comparison using arrays of dots presented on cards.  Cards present groups of differently colored dots at different ratios, and kids sort cards by the color of the more numerous dot array.  We have a very fun oversized version with an oversized timer so that it’s super interactive and physical.  This is a game we’ve used in experiments in the field to exercise numerical intuitions across a very broad age range, from about three years to adulthood.

Raffle for Shapes of Constant Width: We plan to give away some sets of shapes of constant width with our lab and MoMath’s logos printed on them (like what we give away to study participants in the museum).  Anyone interested can enter the raffle and we’ll choose winners.  We’ll make sure they get their prizes either that day or in the mail after the event.
