I started teaching PY/PM as a junior. I taught four different classes of second graders. I absolutely loved it!! Now, as a senior, I have taught a first grade class and am starting a fourth grade class. I've seen how much these kids learn from this...I even had a kid last year whose dad was an alcoholic, and I think he really learned a lot about the problem. PY/PM is so fun to teach, and the kids really love it.
