That’s straight from the website of DonorsChoose.org where you can donate money to individual classrooms. Teachers can register their projects, the amount of money they need, and donors can literally sift through all the projects and donate any amount to specific projects they want to fund.
You can search projects by Resource type (tech, books, supplies), or search for projects by teachers who have never been funded before or projects that have received no donations. You can also search by age group (prek-2, 3-5, etc) or subject (donate to STEM subjects? Books for classrooms?).
If you’re a teacher with a project that’s really worthwhile that you can’t get off the ground, Donors Choose may be a good resource, and if you’ve got some money budgeted for donations every month, here’s a good place to find teachers who need support! I’ve been seeing this org around on Twitter lately, what with defunding of the arts and conversations about girls in STEM, inequality in classrooms, and this is a good way to do something small and make immediate impacts in the classroom. So have at, friendos!
