Surprise! You're teaching today.

So today I came in expecting to do my usual observation in the back of the room. Mr. Z decided that I would be going through two worksheets while he wrote a lesson for his APPR observation on Wednesday. He gave me two work sheets to do with the students on opportunity cost. I read through the instructions with the students and helped them fill it out. Had I been told in advance that I would be teaching I would have created my own materials to supplement these sheets. I had a feeling I wouldn't make it to the end and suggested that I should go over current events with them. He ensured that I would have enough to do. The lesson went alright, as engaging as a worksheet can be. I looked at the clock when I was done and five minutes remained. I actually said out loud to the students, "oh crap, here are those five minutes again." At least I can laugh about it. I shouldn't be so hard on myself because everything else went fine. It's just that I need to work on pacing. Mr. Z could have drawn out those worksheets for double the time I taught them, with lecture and notes. My style is to just get it done and move on to the next thing. That's what I did. I think if I had more content knowledge to draw upon I would have been able to fill up the time. I can't wait until I know this content as well as these veteran teachers, but that will take time. If I had known I would be teaching today I could have created an activity to do to review the terms or add multimedia. I can't wait until I have my own class, where it's no longer a surprise that I am teaching, as that's what I have been hired to do.
