Well am not that old, just a few years under 50 but methinks I did go to some relic-like schools in Ontario.
In late 1960's, we still had wooden desks with drop down desklid.

And in 1970, I remember the girls had to kneel and female teacher would check to ensure our skirts were long enough to touch /graze floor. Yes, mini-skirts without pants underneath in winter time, were a no-no.
