MoMath January – February 2025 Upcoming Events
Happy holidays! MoMath is OPEN EVERY DAY this year — join us after the kids have opened the presents, or as a precursor or post-celebration to welcome in the New Year.
As we head into the final weeks of the year, MoMath is brimming with exciting events and activities that will keep you engaged and inspired. Kids can kick off the holiday season at MoMath’s Puzzle Adventure minicamp, where games and challenges ignite creativity and sharpen problem-solving skills; educators can go to infinity and beyond in an engaging day of professional development; adults can learn Bulgarian solitaire and explore Dynamic Dice in an online community of lifelong learners; and teens and tweens can investigate something that’s “Knot So Simple” before enjoying a social night all their own. Plus, everyone is invited to help us fill the room as we investigate the birthday paradox: if your birthday matches someone else’s, you’ll both go home with a MoMath t-shirt! And all are welcome to enjoy a Night at the Museum with a talk on mathematical art followed by the Aftermath, where a mashup up math and music, dancing and drinks, and food and friendship combine to make a night to remember. Whether you’re solving puzzles, exploring the infinite, or enjoying a night out, there’s something for everyone this winter at MoMath.
MoMath on Fifth, a pop-up experience located at 225 Fifth Avenue in Manhattan/New York City, is open for general admission from 10:00 am to 5:00 pm, seven days a week, 364 days a year. Purchase admission tickets, become a member, and check out upcoming events, in person and online!

Title I schools are eligible for free programs and field trips
MoMath’s free outreach programs for Title I schools include in-person and online field trips to the Museum, workshops presented by experienced MoMath educators in your classroom, and visits to your school by Math Midway 2 Go (MM2GO), MoMath’s traveling suite of mathematical exhibits. Support for these programs is now available, thanks to contributions from individuals and organizations including: Judith Gibbons and Francesco Scattone, The Scripps Family Fund for Education and the Arts, Two Sigma, the ADP Foundation, and New York City Council Members Carlina Rivera (Council District 2) and Mercedes Narcisse (Council District 46). These programs are supported, in part, by public funds from the New York City Department of Cultural Affairs in partnership with the City Council. To apply for one of these free programs, visit titleone.momath.org. Interested in sponsoring one of them? Email donation@momath.org.
