Join the Square Giving Circle

The Square Giving Circle is SUMM’s recurring giving community — a group of math lovers, educators, parents, and curious minds who believe that small, steady gifts can make a big impact.

Each time the number of members in the Square Giving Circle reaches a perfect square milestone (4, 9, 16, 25, 36, and beyond), a new puzzle is unlocked for everyone to enjoy. Each puzzle contains a clue to a larger mystery that will be revealed at the end of the campaign.

Check out the puzzles

Our eventual goal is to launch the West Coast’s first math museum, a building in a permanent location with interactive exhibits and play areas that draw connections to music, art, technology, history and science.
