MƒA: Math Trails
The MƒA Math Trails series provides teachers with planned routes that highlight the mathematics found in and around New York City landmarks. Both teachers and their students can follow the trails while answering mathematical questions and making the connection between mathematics and other subjects including art, design, architecture, science, geography and history. Check out our NEW math trail featuring the Bronx Zoo! Also choose from the Rubin Museum of Art, the American Museum of Natural History, the Museum of Modern Art, a NYC Sampler featuring NYU, Columbia and Madison Square Park, a NYC Museum Sampler, or the Ellis Island Immigration Museum.
