When I was teaching, there always items I wanted for my classroom but couldn't afford.
However, if I were teaching today, I would go online to ClassWish.org. ClassWish is a "new nonprofit that provides teachers and schools with an easier, more rewarding and more efficient way to inspire and attract financial support from individuals and organizations in their communities."
At ClassWish.org teachers and school leaders create wish lists of items they need. Once lists are posted, people and businesses in the community can see exactly what is needed and how they can help. These visitors can then contribute online by making a tax-deductible donation for which ClassWish provides a receipt. ClassWish then has the items shipped directly to the schools at no cost to the school or teacher.
With ClassWish any teacher from any school can post a wish list and donors can give to any and every classroom they care about. Anyone can collect donations including principals, administrative staff, and PTA/PTO. Teachers can add as many items to their wish lists as they like at any time and can change the items on their wish list whenever then need to. There are no fees for donations.
Check out ClassWish.org here. I think you'll be glad you did.
