24 Challenge® Math Program

The 24 Challenge® is a tournament-style competition organized around the 24® Game. Millions of students in more than 20 countries have participated since 1988.

Over a period of months preceding the event, teachers use the 24® Game in their classrooms to help students hone their mathematics skills. Then—using the official rules available on this site—schools or districts hold local or district-wide playoffs to determine which students will advance to a Championship Event!
