This nonprofit site helps US teachers in high poverty schools get supplies for their classses. The link here will take you to a simple search for classroom projects asking for assistance, like

seeking books
supporting kindergarten

There are projects listed for St. Louis-area schools (where I am in Missouri), but the organization is open to every public school in the USA. I first learned about it from a story in the St. Louis Post-Dispatch. That’s the good news! As always, help when and where you can.
