“Several studies suggest that providing more time for physical activity (by reducing class time) can lead to increased test scores, particularly in the area of mathematics. For example, in one of these studies, students placed in an experimental group engaged in 24 minutes of additional physical activity per week—and had a corresponding decrease in class time for academics. Mathematics test scores in this group were consistently higher than for students in a control group, who saw no change in time allocation.”
