I spent my first grade in a one room school house. There were 3 children in Grade 1, 2 in Grade 2, 2 in Grade 3, no Grade 4's, a whopping 4 in Grade 5, a pair a twins in Grade 6, 2 in Grade 7, one in Grade 8 and 1 taking Grade 9 by correspondence. And most of them were my relatives! There was one family that still drove their horse and buggy to School in Autumn and Spring. Yes, I remember playing the games, and swings with a cement pad underneath.
The next year, we were bussed to 'town school'. Two grades in each room until Grade 6, when the new school was built. Mine was the largest graduating class up to that time for our school--31 in Grade 12.
