I'm student teaching in a third grade classroom right now. With my degree, this is the highest grade level I can teach. My CT and I get along just fine, but I feel like I'm always trying to impress her, so I feel intimidated. I'm slowly taking on subjects until I start taking them all over after next week. This past week, I took on math in addition to social studies. My first math lesson was a disaster. I was teaching rounding, and our book didn't give me any concrete rounding rules, so I looked online and found some. The rules I taught on day one were different than what my CT has taught in the past, but we didn't realize it until afterwards. The kids were just so confused. I didn't give them enough practice time and I just talked and talked. My CT told me that math is all about the kids practicing and gave me tips for the next day. I went around during Daily 5 to re-teach the concept to a few students. The next day came, I retaught rounding with new rules, gave the kids their own rounding rules card, and used some of her strategies. Still, I moved too quickly into the kids working in pairs. I still didn't give them enough guided practice and completely missed 2 out of 3 concepts that I was supposed to teach. I caught myself on one, so after I handed out their seatwork, I did a few of the 3-digit roundings together. The kids were still confused. So, yesterday, I had a little over an hour for math. I decided to review some 2- and 3-digit rounding problems before I dived into the estimating sums lesson because I felt the kids really needed it. We worked on a few problems, and then we learned about estimating sums. We did 10 or so problems together. I ran out of time, and I gave them their worksheet with little time to really complete it. The kids were STILL so confused. Even though we talked about rounding BEFORE adding, they got their worksheet and just didn't know what to do. I feel inadequate. I feel like I'm not teaching it well. I have to keep reminding myself that they're only 3rd graders. For some reason, in my head, I was thinking that I didn't have to break things down for them in steps like I would 2nd graders. I know now that I have to take it slow with them. I'm just afraid I'm not teaching them well. I'm afraid I'm not a good teacher. Monday is estimating differences, and I'm worried that I'm going to lose them again. My confidence has dropped to zero. What can I do to improve? I reflect on my lessons, and I know what I do wrong. It's just that when I'm up there in front of the students, I forget some of the things I'm supposed to do or not do.
