XtraMath

XtraMath® is a 501(c)(3) nonprofit organization dedicated to math achievement for all. Our goal is to develop effective, efficient, adaptive, and intrinsically rewarding supplemental math activities. XtraMath started in the fall of 2007 when David Jeschke, a computer programmer, volunteered at a local elementary school and recognized the need for an individualized math practice program. XtraMath spread rapidly to other classrooms by word of mouth and the program continues to evolve. Localized into 12 languages, including American Sign Language, XtraMath is now used by millions of parents, teachers, and kids around the world.
