Discover Fraction Ball

  • "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
