Proof School is part of a community that is rooted in the world.  

We start in the classroom, but our mission carries us beyond the walls of our school. 

We promote math and math education through partnerships with schools, institutions, and organizations. Our goal is to develop life-long learners by connecting our students, our families, and our supporters to events, fairs, and opportunities.
