Local Business Sponsorship 
Local businesses are usually delighted to support specific teachers in specific classrooms, especially if they can get some good will press coverage as a result. Last April during Math Education I tested this idea and got some surprising responses - many businesses were DELIGHTED to support the classrooms even without the PR. Over a dozen classrooms were recipients of a Topic Package from The Algebra Game. The businesses were active in the local communities; some were the already defined school business partner and some were not. I recommend this avenue as a successful connection to your community, especially if the math teacher stays in touch with the sponsoring business.
