A bicycle with square wheels sounds like a design mistake. At MoMath, it is an invitation to ask a better question: what would the road have to look like? That change of perspective is the museum’s appeal. You come to play with an idea, not to prove that you remember algebra.
At a glance: The National Museum of Mathematics is now at 635 Sixth Avenue, at West 19th Street. Online admission is $33 for adults and $22 for ages 2–17; regular hours are 10 a.m.–5 p.m. Allow about 90 minutes to two hours for a focused visit.
A museum for people who like asking “why?”
MoMath turns patterns, shapes and motion into things you can investigate. Its square-wheeled tricycle is a particularly memorable example: the museum’s coverage of the new location confirms that this favorite moved with it. The interesting part is not simply taking a turn. It is noticing what makes an apparently impossible ride work.
The official interactive exhibit guide is a useful preview. Pick something that makes you curious, try it, and then look for the explanation. The explanation has a much better chance of sticking once you have a question of your own.
For a parent, the temptation is to become the teacher. Resist it for a few minutes. Let a child make a prediction, get surprised and try again. “What changed?” is often a more useful prompt than “Do you understand?” A failed attempt can be the best part of a hands-on museum.
Who is likely to enjoy it?
Our strongest recommendation is for curious school-age children, teens who enjoy puzzles, and adults willing to experiment. Younger children can explore with an adult, but a toddler’s visit will be different from a ten-year-old’s. This is an editorial assessment, not a minimum-age rule.
It can also make an unusual daytime date: you have something to do together and something to disagree about that is less consequential than where to eat. If your ideal museum visit is quiet contemplation in front of paintings, compare MoMA or the Whitney instead. MoMath is not another name for MoMA.
Tickets: do the easy arithmetic first
| Visitor | Published online admission |
|---|---|
| Adult | $33 |
| Youth, ages 2–17 | $22 |
| Full-time student with ID | $22 |
| Senior, 60+, with ID | $22 |

Two adults and two children aged 5 and 10 add up to $110 in listed online admission. A couple pays $66. These are admission subtotals, excluding food, transport and any separately priced activities. The official booking page describes these as introductory online prices and adds $1 per ticket at the door.
Advance tickets are redeemable within 30 days of purchase, subject to capacity and opening arrangements. The museum states that purchases are nonrefundable, including when free-admission periods or partial closures occur. Wear closed-toe shoes to make full use of the activities. Children under 16 need an accompanying adult.
Check the calendar before buying
The regular schedule is daily, 10 a.m.–5 p.m., with Thanksgiving closed. Math Encounters and other events can bring early closures. As of our check, October 14, November 4 and December 2, 2026 have a 2:30 p.m. closing.
A free opportunity: the museum lists Free Play on October 29, 2026, from 3–7 p.m. That is a dated event, not a weekly Thursday promise. Use the visitor page and event calendar for the next dates. General admission and a special program can have different arrangements.
A 90-minute visit that leaves room to think
Spend the first ten minutes looking around rather than joining the first queue. Let each person choose one exhibit they want to try. Give those choices most of the next hour, with time for a second attempt instead of treating every station as a race.
Use the last twenty minutes to return to the idea that surprised you most. Ask someone else in your group to explain what they noticed. You do not need to leave with a formula memorized; a good question is a perfectly respectable souvenir.
For photographs, look for hands at work, unusual shapes and a child’s reaction rather than another posed family lineup. Follow the museum’s rules, avoid photographing other visitors without permission and put the phone away when it is your turn to experiment.
Pair it with air, food and a shorter second stop
The new address is on Sixth Avenue at 19th Street, so do not navigate to the founding East 26th Street site shown in older articles and videos. Open the current address in Google Maps.
After an indoor visit, make the next part of the day simpler. Our High Line guide offers a West Side walk; Little Island is another outdoor possibility when the weather cooperates. Choose one, allowing for the journey, rather than treating them as exhibits next door.
Arrange food through our kosher dining guides and use New York with kids to compare the day’s pace. For Shabbat-observant visitors, choose Sunday through Thursday outside Jewish holidays. If step-free access or specific sensory needs are essential, confirm the new building’s arrangements with the museum before booking.
Keep exploring the ideas
The museum links to recorded programs and talks. These are deeper mathematical explorations rather than a short building tour; some require payment or membership. Choose a subject that interests your family instead of assuming every recording is a free preview.
Frequently asked questions
Where is MoMath now?
635 Sixth Avenue, at West 19th Street in Manhattan. This is the current location, not its original East 26th Street address.
Do we need to be good at mathematics?
Curiosity matters more than speed at arithmetic. The visit is built around exploring and experimenting; adults can help younger children work through the ideas.
How long should we allow?
Our suggested first visit is 90 minutes to two hours. Leave longer if your group enjoys repeating activities or attending a separate program.
Is entry always free on Thursdays?
No. Free Play is offered on specific published dates. Consult the calendar rather than assuming a weekly free session.
