Stop by on July 12 and check out this year’s fun festivities!
Experience hands-on mathematics!
Come explore how mathematics illuminates the patterns that shape the world around us.
Spend a day at the NYC Math Festival and discover a side of math you’ve never seen before: explore MoMath’s dynamic exhibits, take part in inspiring activities, and have an experience you’ll never forget.
Just a sample of the fun that awaits…
Step right up to Self Reflections for a kaleidoscopic selfie of symmetrical patterns.
Love patterns and shapes? Twist ‘n’ Roll lets you twist shapes apart and change how they fit together to make dramatic changes in how they roll.
Let your mathematical mind run free with DoDecArt, and discover the many features of the dodecahedron as you create captivating dodecahedral structures.
Build up and out — with math!
See the mathematics of architectural design in action as you work together to build the giant Leonardome, a construction with various patterns based on the ingenious designs of Leonardo da Vinci and one of MoMath’s most popular birthday party activities.
Get your hands on MM2GO, MoMath’s traveling exhibition
MoMath’s array of dynamic activities from the Math Midway 2 Go (MM2GO) traveling exhibition will amaze you with the joy and beauty of hands-on mathematics:
Guests of all ages can enjoy a 120-foot-long trip along MoMath’s iconic Number Line Tightrope.
Create tiling patterns called tessellations and a panorama of patterns using brightly colored and unusual magnetic shapes with the Miles of Tiles.
Slice shapes with lasers in the Ring of Fire.
Design a roller coaster with Roller Graphicoaster!
Explore giant mazes, plant the daisy, crank up the math tunes, make the moon magically disappear, and more… Enjoy these and other MM2GO classics.
Enter the drawing for a free year of admission and more!

Let’s Play Math with Tulipán
The Tulipán Foundation returns to the 9th Annual NYC Math Festival with an interactive pop-up inspired by Hungarian mathematician Zoltán Dienes. Developed with math educator Megan Siedman, “Let’s Play Math with Tulipán” invites visitors of all ages to explore three lively stations: a flower garden blooming with creative puzzles, a giant city building team race, and a tent dedicated to Dienes’ colorful attribute blocks, complete with life-sized Venn diagrams and challenging strategy games. Rooted in Dienes’ belief in learning through play, each station transforms abstract math ideas into hands-on fun with a distinctly Hungarian twist on MoMath’s free, family-friendly celebration of mathematics.
Get your Minds On Math with the Lab for the Developing Mind at NYU
Children can build the NYC skyline in Multiplication City by rolling dice, multiplying numbers, and creating colorful skyscrapers. They can also race against the clock in Speed Sorting, a fast-paced game that exercises number sense using oversized dot cards and timers. Families may enter a raffle to win intriguing “shapes of constant width,” mathematical objects featured in research conducted in collaboration with the MoMath.
Math Play with MathHappens
MathHappens Foundation promotes informal, hands-on math engagement for learners of all ages. Emphasizing screen-free activities that are easy to begin and rich in mathematical depth, MathHappens encourages persistence through thoughtful exploration.
The Mathematics of Juggling, featuring John Chase
As he tosses clubs and balls in crowd-thrilling arcs, math educator and juggler extraordinaire 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.
Construct the Hyperbolic Rainbow, with Chaim Goodman-Strauss
Work together with others to assemble puzzle pieces (cut from foam playmats) to create this frilly mathematical form found throughout nature that demonstrates the negative curvature of hyperbolic geometry. What is hyperbolic geometry, you ask? MoMath’s Outreach Mathematician, Chaim Goodman-Strauss, will show you!
Russian School of Mathematics
Kindle your passion for math and get to know the Russian School of Mathematics, an after-school enrichment program with a unique approach and five locations throughout the NYC area. Enjoy hands-on math games and fun activities that challenge you to think logically and critically!
Plus, so much more!


This is a free, rain-or-shine event, open to the general public. No registration is required — just come on by!
