What were classrooms like in the 1950-60s elementary schools?

I guess elementary is like primary or prep in England? Rows of wooden desks with lids that lifted, to put books in, hard, sometimes splintered wooden bench to sit on.. teachers desk on a raised platform at the front. Black board and chalk, boys in shirt and tie, extremely short grey trousers, knee socks and shiny shoes,. Teacher in suit with black gown. A slipper or cane available for punishment.
