Donorschoose.org allows a teacher to supplement the funding received for classroom supplies. Go to donorschoose.org, enroll and submit a proposal. The first three times you apply, there is a limit of $400, then $800 then I believe there is no reasonable limit.

In these times teachers need to be proactive in obtaining supplies and equipment. If the funding from the state is relied upon, the amount of money for special or exciting supplements to the regular program will not be funded (let alone basic supplies it seems these days)
