NYC Math Festival

Summer readers may get all the attention, but let’s not forget about the more mathematically inclined amongst us. That’s exactly the point of the free National Museum of Mathematics’ NYC Math Festival, an all-ages takeover of puzzles, patterns and hands-on problem solving. On July 11, New York City Lab School for Collaborative Studies (333 W. 17th St., between 8th and 9th Avenues, and entrance on W. 18th St.) transforms into an interactive playground where visitors can step inside geometric constructions, tackle collaborative challenges and experiment with large-scale installations designed to make abstract ideas feel physical. Part street fair and part brain teaser marathon, it’s built for families, puzzle lovers and anyone who’s ever enjoyed the quiet satisfaction of cracking a good problem.
