This month's theme is about integrating movement across the school day. It's a theme that aims to look at not only why physical activity should be incorporated into and across the school day, but also how it can be.
Regarding the why, the research is pretty solid. There are cognitive benefits associated with physical activity, including improved memory, concentration, attention, and academic performance. All of these (and other) benefits were succinctly summarized by Charles Basch back in May 2010 with his publication Healthier Students Are Better Learners: A Missing Link in School Reforms to Close the Achievement Gap.
