First week is done

I made it through the first week of student teaching with only a couple of bumps and bruises. I was able to go through the schedule today, going from room to room, without looking at the printed schedule. I know the names of most of the students I will work with. And I'm starting to understand what my roll is in their school day. I do feel like the teaching part is not going to be a problem. The university assignments on the other hand are scaring me; progress monitoring, behavior management, assessments, writing an IEP.
Hopefully my co-operating teacher, Kelly, will be feeling better by Monday and will be able to come to school. I am ready for direction and instruction from her.
It was frustrating today, to watch the math lesson; three inches on a four inch line is not three fourths, it's three inches; seven inches on a ten inch line is not seven tenths, it's just seven inches. I don't feel it's my place to contradict the teacher, but I should have said something. The idea was to use the same length unit (a foot) and divide it into different sizes (halves, thirds, eighths) to show how the same size unit can be divided. That's going to have to be re-taught.
I think the worst part of the week was the two occasions when students flat out refused to do what I asked them to do. I will definately have to think about what I am going to do in the future as a student teacher and in my own classroom in these situations. I don't feel comfortable going to the student's regular teacher but that is what I did this week. I think doing that shows the students I'm not really in charge, and indicates to the teacher that I'm not capable of handling it. It undermines me. At this point I don't know what behavior management procedures are being used. I felt really frustrated and at a total loss when the students just plain said no and refused to budge when I gave them directions. From my last semester experience, I learned that it is not good to cottle the students and that is what one teacher has observed about new teachers she works with. I try to think, "how would I handle this situation with my own children." That doesn't always work because I can't yell at the students and I can't pick them up and carry them. Hmm, do I treat the student's with more respect than my own children?
I have concluded that the professors are teaching us how to have the most ideal classroom. What I noticed this week is, classrooms don't work like that. Student's don't sit and pay attention perfectly. Teachers don't teach perfectly, it's ok to not know it all. And classrooms don't run without glitches. I should strive for the ideal classroom but I shouldn't get too discouraged when things don't go perfectly. Even the seasoned teachers I have observed this week, have lost instructional time for one reason or another and students waste time.
