XtraMath is a 501(c)(3) nonprofit organization that provides an online supplemental math program for students in grades K-8. Our online math fact fluency program helps students develop fluency with addition, subtraction, multiplication, and division facts and build the computational memory that enables greater success in higher-level mathematics.
XtraMath is dedicated to math achievement for all learners. Our goal is to develop effective, efficient, adaptive, and intrinsically rewarding supplemental math activities. Xtramath's purpose is to provide equitable supplemental math activities that connect with all learners. We offer schools, teachers, students, and families easy, simple, and effective math programs in areas where students struggle or need more practice.
XtraMath was founded in 2007 by David Jeschke, a former Microsoft programmer and startup developer. While volunteering as a math tutor for Seattle elementary school students, he found many still counting with their fingers and recognized the need for an individualized math fact practice program; thus creating XtraMath. In 2009, XtraMath became a nonprofit organization and, through a grassroots movement, has grown to be one of the most widely used math programs in schools today.
David was a software programmer at Microsoft before founding XtraMath. David has a master's degree in computer science from The University of Texas, Austin.
Sabareesh also advises several pre- Series A startup companies and sits on their board. His expertise includes portfolio management, business strategy development, P&L ownership, M&A, scaling up seed -stage companies, and fundraising.
