Inexpensive Whiteboards "Here's a way to get cheap whiteboards for every student. Go to any building supply store and purchase a large sheet of white board for around $10 and take it to the cutting department. Let them know you are a teacher and need it cut into enough squares for each student. Hopefully, they'll cut it for you for free. Take colored electrical tape and cover the edges. Each student will have a whiteboard for classroom use, therefore, cutting down on paper usage."
