How Fraction Ball Works

  • Fraction Ball is a team basketball game where 4th and 5th graders master fractions through play, replacing math boredom with real confidence and hope.

  • Students add, compare, and convert fractions as they track their team’s score. The math is core to the game itself, not an additional lesson plan.

  • The Fraction Ball Mat brings the action indoors. Unroll it for a 20-minute session, then roll it right back up. It seamlessly with any workshop rotation.

  • Structured, self-managed, and simple to run. Backed by peer-reviewed research, Fraction Ball delivers high-energy math learning without classroom chaos.

  • "Students wanted to win, and they wanted to make sure that they got the amount of points that they earned. It was a lot of mental math and communication. More than anything, I saw a lot of collaboration, communication, critical thinking on their feet."

    — Guadalupe Cruz, 5th Grade Teacher at El Sol Academy

  • "There was a student in particular who was very frustrated at the beginning... Then little by little I saw his confidence growing and he was convinced that he could do it. That confidence he gained on the court is carrying over into the classroom."

    — Ivet Gonzalez, STEM Specialist at El Sol Academy

  • "With my class, their math skills were improving a lot faster with Fraction Ball versus doing the regular work we normally did the last few years. My kids convert fractions greater than one a lot quicker than they did before; more automatically."

    — Anonymous, 4th Grade Teacher
