When I was a kid, I remember my teacher had the whole class run three laps around the schoolyard before school even started. The boys got an extra lap, sometimes two. There were no problems with disruptions in class that I can remember.
Thank goodness things like recess and dodgeball are still status quo in this school district. The elementary school is right on Rte 13, and so it is not unusual to drive by and see several classes outside for recess at various times of the day. PE classes at all 3 levels of school are also regularly held outside, weather permitting.
Except for an assinine and archaic policy in regard to headlice, this district is not quick to seek drug remedies for problems. Thank goodness. I am working on the ignorance of current public health knowlege that shows the district no nits policy and policy of pushing antibiotics for lice are far more detrimental to the children than the stupid bugs themselves.
