Three ways to work with Proofstone.

• High school math courses

  For microschools, hybrid schools and small international schools

  Complete Pre-Algebra, Algebra 1, Geometry and Algebra 2 courses, each with a video lesson for every class day, a day-by-day facilitator guide, practice, and tests with answer keys, so an adult who isn't a math specialist can teach it well. Founding seats for fall 2027 are $150 per student for the year.

• AI for math teachers

  For math teachers and the schools that support them

  Professional development on using AI well in math teaching: planning lessons and making materials faster, catching the math it gets wrong, and setting clear rules for how students use it. Available online, in person or as coaching.

• Interactive lessons

  For teachers, schools, tutoring programs and online courses

  Browser-based lessons that let students work out a hard idea step by step, like why a circle's area is πr². Each one is built to order for the topic your students find hardest and opens on any device, with nothing to install.
