Teachers, this year you can sign up your class - student registration is just $5π. Students can sign-up individually through this registration page or you can contact Pete Grostic, pete@:mathmedicfoundation.org, for bulk registrations. Ask your administrator or PTO if they'll cover the cost for your class. Each fee goes to a great cause - helping students, teachers, and schools in need. 100% of proceeds will go toward helping students and teachers with math resources, materials, or professional development. There will be a price increase to $12π for adults and $7π for students starting Feb 17, 2026.
