Happy Thanksgiving to all my American readers, and hey, everyone else too — gratitude is global.

In the US, this is the start of the season where people customarily think about their charitable gifts for the year, so here’s a few math-related places you could think of donating:

The Prison Mathematics Project supports mathematics study for inmates.

Bridge to Enter Advanced Mathematics (BEAM) runs math enrichment programs for low-income students.

And of course the good old American Mathematical Society continues to roll on supporting the American math community in innumerable ways, as it has for more than a century. You could donate money, or, if you’re a mathematician who’s not a member, you could join!
