The Square Giving Circle
The Square Giving Circle is SUMM’s sustaining donor community. Anyone who becomes a recurring donor, whether giving monthly or making a paid-in-full annual recurring gift, is invited to join the Square Giving Circle. Your ongoing support ensures SUMM can plan ahead and say yes to more partnerships, more school visits, + more free community programs.
Square Giving Circle members enjoy:
Exclusive quarterly puzzles created for Circle members

Recognition as sustaining supporters of joyful, hands-on math
Puzzles
We kicked off the Square Giving Circle with a series of 10 puzzles. Each of the first 9 puzzles contains a clue to a larger mystery in a final Meta Puzzle.
This December, thanks to incredible support from across our region, we grew from just 9 recurring donors to 45 — a 400% increase in dependable, year-round support. These 45 donors will bring SUMM more than $11,000 over the next year. Their generosity strengthens SUMM’s ability to plan ahead and bring joyful, hands-on math to more students, families, schools, + libraries.
To celebrate this milestone, we will release a puzzle each Wednesday for the rest of December. On New Year’s Eve, we will reveal the Meta Puzzle (though Square Giving Circle members receive early access as soon as they join).
