The following are organizations that donate goods to classrooms:

Donors Choose – public school teachers can post online requests for equipment and supplies.

Adopt A Classroom – offers a free, safe online e-wallet account to educators who want to solicit financial support from the community. Teachers can use the money to purchase books, games, and other educational supplies through the online vendors associated with the site.

Freecycle – people from all over the world post books, CDs, electronics, and toys they’re giving away. The only catch is that you have to pick up the items.

Kids in Need Foundation – has a network of 25 free school-supply resource centers around the country.

Digital Wish allows teachers to create a classroom technology wish list that supporters can browse and fund.
