Here is an article that I found online that really backed up the positives of kids getting to PLAY. Here is the link to read the article in its entirety.
As schools cut down on physical education and recess, kids are spending more time than ever in a desk. And while nerdy second-graders like me didn't ever consider arguing for more gym, there's increasing evidence that being active helps not just children's waistlines but their brains.
"If you consider the anthropology of humankind, we were designed to move,"Charles Hillman, a professor of kinesiology at the University of Illinois at Urbana-Champaign tells Shots.
Hillman and colleagues have added more evidence as to how activity helps kids. Hisstudy, published Monday in Pediatrics, shows 7- to 9-year-old children who run around and play like, well, children, for at least 70 minutes a day show improved thinking skills, particularly in multitasking, compared to children who aren't as active.
The researchers looked at a nine-month after-school program, called Fitness Improves Thinking in Kids (FITKids) at the University of Illinois. The 109 students met after school nearly every day for a snack and a quick lesson on fitness and nutrition. Most importantly, the children spent 70 minutes running around and playing tag, soccer, jump rope and other games. The focus was not on competition, but playing like kids normally do.
