You know how teachers are always spending their own money on fun things for their classroom? Fun things like paper and books? Donorschoose.org is a brilliant site that lets you fund classroom projects. Teachers submit requests, and you decide who gets your cash. One teacher in San Francisco wants to take the kids to see a play, another in Brooklyn needs a $365 video camera so the kids can see their choral performances. Let's all throw $20 toward keeping the arts in our schools.
