Number Ninjas: educational math practice for schools

Number Ninjas is an educational mathematics application for schools, teachers, and students in K–12 education. It supports arithmetic instruction through focused practice in addition, subtraction, multiplication, and division. Students work on math facts, build fluency, and practice toward mastery at a pace appropriate to their learning needs.

Teachers can use classroom assignments, repeatable diagnostics, and progress reporting to guide instruction and review student learning. Google Classroom integration connects authorized classrooms with roster and assignment workflows. School access is governed by classroom authorization; signing in alone does not grant access to student records. A separate guest option offers practice without a Google identity or access to classroom data.

The application uses game mechanics, a retro desktop, and character rewards to make math practice engaging. These features serve the learning experience: Number Ninjas is not a general-purpose gaming website or a portal to unrelated games. School IT administrators can review network requirements, privacy information, and the school agreement before deployment. Choose Play for Free to start the learning application.
