Education Oberservation Class

I am an education major and for one of the classes I am taking we go to other schools and get to observe a teacher there. So far I have observed a 6th grade math teacher, a high school medical procedures teacherm, and a 5th grade english teacher. I really like observing the teacher an with have such a wide variety of subjects and grades it helps me decide more of what I am wanting to teach. I think I would like to teach a 7th grade math or history class. I would prefer teaching math over anything else. With observing these classes I have also realized that I would like to teach upper lever elementary and into the middle school level grades.
