My observations over the years confirms the importance of space for children. Those blessed with the chance to attend schools where there is space to play do not know how lucky they are.
Green grass, trees and ovals make a difference. Those who are crammed into classrooms and buildings with little adjoining space miss out desperately.
Environments cannot always be controlled. Space is available only where there is space. Educators and school administrators would be well advised to make cribbing on space for the sake of building and amenity expansion, their last priority.
Once lost, a space is gone forever.
