Key Facts

Overview

The term 'XtraMath guy' commonly refers to David Moss, the co-creator of the widely used math education platform XtraMath. Launched in 2007, the program was designed to improve elementary students' fluency in foundational arithmetic operations through structured, daily practice.

XtraMath gained traction in classrooms due to its simplicity, accessibility, and research-backed approach to building math fact mastery. The platform is free for teachers, students, and parents, making it a popular tool in public schools across the United States and beyond.

How It Works

XtraMath uses timed assessments and daily practice to help students build speed and accuracy in basic arithmetic. The system adapts to individual progress, ensuring mastery before advancing to more complex operations.
