The U.S. requires its students to take a full menu of mathematics — one size for all — with no alternatives or exemptions. Colleges set similar hurdles. Author and professor of political science Andrew Hacker, who also teaches a course in mathematical literacy, asks one simple question: Why?

James Tanton, mathematics educator, consultant, author, and the Mathematical Association of America’s mathematician-at-large, responds with his own question: Are people missing the point of what current high school mathematics is actually about?

“Executives from New York’s National Museum of Mathematics – or MoMath – visited the International Grammar School [in Sydney, Australia] on Wednesday morning to see the school’s new STEAM program in action. MoMath’s executive director, Cindy Lawrence, said that engaging young people to make them interested in maths and other STEM subjects was crucially important. ‘In our museum, we actually have an art gallery. That’s how closely we think art and math are related,’ she said.”

WALKS OF NEW YORK, MARCH 31, 2016

“At MoMath the formulas you learned in school come to life in a series of interactive exhibits. Great for all ages, you can take a ride on a bike with square wheels, see how light and color can be manipulated through mathematics, and create geometric sculptures.”

NEW YORK TIMES, FEBRUARY 2, 2016

“The Beaver Run exhibit is based on Truchet tiles popularized in 1987 by Cyril Stanley Smith, a scientist at Massachusetts Institute of Technology. On each tile, two quarter-circles connect midpoints of adjacent sides.”

THE WALL STREET JOURNAL, MARCH 4, 2016

“Last week, the museum held its 2016 MoMath Masters competition. The overall winner was Po-Shen Loh, a Carnegie Mellon math professor. In second place was Two Sigma’s Daniel Stronger, a quantitative analyst with a Ph.D. in computer science, and in third was Ken Perlin, a computer science professor at New York University who invented something called ‘Perlin noise’ that makes textures look realistic in computer games.”

“Another way MoMath is changing the conversation about math is by encouraging parents to integrate math into everyday life. ‘Reinforcing your child’s math skills is as easy as searching for shapes around the neighborhood or finding math role models that kids can look up to,’ Lawrence says.”

DARIEN TIMES, MARCH 10, 2016

"Grasso said this is part of an effort to make math more exciting and accessible for students at all grade levels. ‘You’ll remember this. You might not always remember that lesson you learned just because you have to take a test at the end of the week. But this is memorable.’"

BBC WORLD SERVICE, MARCH 14, 2015

“Pi is a number that shows up in a surprising number of different places throughout math, throughout physics, but more than that, pi is actually the essence of what a circle really is. … I think math is worth celebrating, and anything that catches the public interest and helps give the public a glimmer of how cool math can be is worth celebrating.”

NEW YORKER, AUGUST 27, 2015

“‘I have some ideas about what we’re going to do today, but I don’t have a complete idea,’ Honner told his forty students [at the second MOVES conference], who ranged in age from about ten to six times ten. ‘I’m hoping we can play around, and you can invent your own games and go off and explore.’”

THE RECORD, MARCH 13, 2015

“Cindy Lawrence, MoMath’s executive director and one of the organizers of Saturday’s event, said that public celebrations of math can be eye opening for many young scientists. ‘I think it sends a powerful message, especially to the kid who’s in seventh or eighth grade and really loves math but feels maybe a little isolated,’ she said.”

SCIENTIFIC COMPUTING, JUNE 19, 2015

“The exhibits invite participation, encourage experimentation and, hopefully, spark curiosity. Small touches, like handles forming the symbol for pi on the front door and pentagonal sinks in the bathrooms add to the fun.”

CBS NEW YORK, MARCH 14, 2015

“Kids at the museum played circular games with circular candy as they learned the formulas to estimate pi. ‘I like to think about the math of it, I think it’s pretty cool,’ Haddon Township resident Katie Cona said.”

“Join hundreds of other revelers in Madison Square Park at 9:26 p.m. to watch — and perhaps even take part in — a glow-in-the-dark demonstration on the meaning of pi coordinated by the National Museum of Mathematics.”

SMITHSONIAN.COM, MARCH 13, 2015

“Pi appears in the Fourier transform because one of the component parts, or expressions, of the formula is associated with sine and cosine and the angles created by a particle traveling around a circle. ‘Whenever you have a formula that deals with circles or angles, you are not going to be surprised when pi shows up,’ Whitney says.”

“Pi fans can celebrate this weekend with a wealth of math- (and baked goods–) related opportunities. … The National Museum of Mathematics in New York City, for example, will gather people in Madison Square Park to light up a circle around the central fountain and compare its circumference with the distance across it—accompanied by free hot chocolate and *pi*e. “

RAYCOM NEWS NETWORK, MARCH 13, 2015

“The National Museum of Math in New York declared this Saturday as the “Pi Day of the Century,” because the year is 2015, and the calendar aligns with two additional digits of Pi, 3.1415. Most of us won’t make it to the next one in 2115.”

NEW YORK TIMES, MARCH 12, 2015

“You’ll see that 3.14 is pi, the ratio of a circle’s circumference to its diameter. That makes March 14 Pi Day, which this year the National Museum of Mathematics calls the Pi Day of the Century. … Thus on Saturday, the museum has planned a grand celebration, starting at 9 a.m. in Madison Square Park, where even small children can help form circles.”

USA TODAY, MARCH 11, 2015

“The National Museum of Mathematics has already run out of red pizza Pi cutters, though you can still get one in black. The handle is in the shape of the 16th letter of the Greek alphabet, ? (pronounced pi), making it the perfect tool for divvying up a dish of saucy dough while contemplating the ratio between its circumference and diameter.”

WALL STREET JOURNAL, MARCH 4, 2015

“Some of the best minds in investing came together last week to compete for the ultimate title: Master of Math. The annual event—a casual but intense math competition hosted by the National Museum of Mathematics—is the closest thing these quantitative investors, or quants, have to a Super Bowl.”
