Pi Day details

6:00pm – The Art of Teaching without Teaching

MoMath is delighted to host Tetsuya Miyamoto, renowned Japanese educator and inventor of the world’s fastest growing (and most fun!) math puzzle—KenKen®. Included in more than 150 newspapers worldwide (including the New York Times), and with more than one million puzzles played weekly, KenKen® is also used by more than 30,000 teachers throughout the United States to teach kids about analytical thinking and problem-solving. Come learn from the inventor how KenKen® can revolutionize math by teaching us all how to think…and by making math more fun!


6:45pm – Explore

No observance of Pi Day would be complete without a direct, hands-on investigation of the (edible) area of a section (slice) of a circle, or of the circumference (crust) of a circle. Indulge in your own tasty pi experience, and enjoy a chance to try out MoMath's incredible hands-on exhibits after hours and without the crowds.



8:00 pm – It’s Pi Time!

The Pi Day celebration continues: Join Dave Masunaga on a journey of pi exploration, as he shares some of the oddest facts about pi. What mysteries do origami, Vladimir Horowitz’s piano, and tennis cans reveal regarding pi? What popular foods have amazing pi properties? Can simple square paper-folding be used to demonstrate profound aspects of circle geometry?

The pi fest continues as we learn about some of the most natural occurrences of pi in geometry, including some unusual and rarely discussed properties of pi. Many humorous and off-beat occurrences of pi will be revealed, providing everyone with a wide repertoire of perspectives to last the whole year through.


We look forward to seeing you for a fun-filled evening celebrating pi!
