Mission, Goals, and Purpose

XtraMath is dedicated to math achievement for all. 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.

History

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 recognized the need for an individualized math fact practice program and developed 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.
