Main Line Math Festival

November 2, 2025 @ 3:00 pm - 5:00 pm

Join the Main Line Math Festival for children ages 5-12 accompanied by adults! Older students can help out as assistants.

Come and discover for yourself the joy and beauty of mathematics. Solve challenging puzzles, build tricky structures, learn fascinating magic tricks, create colorful symmetrical artwork, play games, and most importantly, have fun! There are volunteer opportunities for interested high school students (community service credit can be provided).

Register to volunteer (adults or students aged 13+) and have your family attend for free, or buy your ticket and enjoy the festival with your child(ren).

All proceeds from the event will benefit BEAM (Bridge to Enter Advanced Mathematics), a program to help students from historically marginalized communities study advanced mathematics and thrive in STEM.
