I found I could definitely afford teachers' college. After a couple of years, they asked, "Are you aiming to teach in K-6 or 7-9?" I said "7-9". After all, I was too mature for little kids. They handed me a sheet of course names. "This paper lists the courses you must complete". Me:"I thought I would get some choices." They said,"You want choices? Choose K-6" and I did.
I taught the 5th grade for four years. I liked it. I got the class with the lowest average of 4 classes. I liked teaching them and discovered all sorts of skills and abilities they showed.
I got a warning: "This state requires an advanced degree beyond the basic 4 year degree within ten years of beginning teaching." I began graduate school, attending at night. I got a grade of A in my first statistics course. My graduate school advisor told me about a program to get a PhD, the highest degree, with scholarships provided. I applied, got accepted, got the degree, and we moved to another state where I taught teachers for 37 years.
