Why we do what we do at Math Shelf. 

Simply put, we care. Early math is critical to helping children reach their potential & we know that the work we do can make a real difference in their lives. 

Backed by Mission-Driven Foundations

We are honored to be the recipient of impact investments and support from the Valhalla Foundation and the Heising-Simons Foundation.

One of Valhalla’s four core goals is to dramatically improve kindergarten readiness in the U.S., so that all children—and particularly low-income children and children of color—get off to a strong start in learning and life.

Valhalla Foundation has supported The Audacious Project since its inception and has given to several Audacious projects that aim to solve vexing, urgent global problems..


The Heising-Simons Foundation is a family foundation based in Los Altos and San Francisco, California. The Foundation works with its many partners to advance sustainable solutions in climate and clean energy, enable groundbreaking research in science, enhance the education of our youngest learners, and support human rights for all people.


Our team is passionate about eliminating inequities in math learning for children.

We're on a mission to improve math education through scalable technology.  Dr. John Schacter created Math Shelf to eliminate early math achievement gaps, and give every child access to high quality mathematics opportunities to maximize their potential. 

John has trained thousands of teachers and administrators across the United States. He earned his Ph.D. from UCLA in educational psychology and graduated with highest honors in Literature from UC San Diego. Before starting Math Shelf, John served as vice president of research for the Milken Family Foundation, Senior Fellow at Stanford's Educational Leadership Institute, and Adjunct Professor at San Jose State University. Dr. Schacter also served as an elementary school teacher and principal. He lives in Palo Alto with his wife and son.

Preschool mathematics knowledge is a better predictor of elementary school academic success than literacy readiness skills. (Duncan et al., 2007)

We do this for the kiddos.
