XtraMath

XtraMath is a Seattle 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. Our math fact fluency program helps students master addition, subtraction, multiplication and division facts. These facts are the building blocks of a child's math education and are absolutely essential for success with fractions, decimals, multi-digit algorithms and higher-level math.
