We used to play a game called School in a Tent. Aloud we read books written by spanking-obsessed Enid Blyton. Those who read badly were put in detention. This meant that they had to stay in the tent while the others went indoors and had tea.
Corporal punishment was inflicted upon those who broke school tent Rules. In the garden was a tree from which we cut sticks to use as canes.
All this happened about ten years ago when we were in our early thirties.
