Christ. This was one of the great escapes from the everyday monotony of school life, and now they are taking it away? I can maybe see if this is a small school and have a very small and limited space for your students' recess (such as the school I worked at last Spring had no more than 500 square feet for the students to play in, and it was more like a park than a yard. Students were taken out 3 classes at a time max). Hell, dodgeball was a mandatory activity during some periods. And from 5th grade on touch football, basketball or handball was the only activity during lunch periods.
