I went to a one room school house when I was in first & second grade. One teacher, 20 kids, grades one through six. I was the only first grader and the following year I was the only second grader. We moved the summer after second grade and I went to a 'huge' school..... each grade had its own classroom and thier own teacher! There was only one third grade class of 31 kids but to me that was incredible! I was so excited to be with other kids my age!
