I was subbing for a kindergarten class. The regular teacher (let's call her Mrs. T -for teacher) was in the hall outside pulling students one-at-a-time for reading assessments, and she would come in the classroom periodically to "check in" and see how things were going while I was subbing. Well, here are some things that happened: 1. When I first arrived in this class, Mrs. T. was explaining the day's lesson plan for me, but she was doing it in a way like I was a 5-year old. "You have to follow the plan exact, ok?" "So when it says math begins at 9:45, you do math at 9:45, ok?" "When it's time to read to them, the book is right here, ok? Page 2, ok?" etc. As often as she says "Ok?" and the tone she says it in, you'd swear she is talking to a toddler. 2. Her class had "cooperative games" that day. I was not aware of what that was, so I asked Mrs. T. and she looked at me like I was dumb and said "Well, it's only for kindergarten and you must have taken a kindergarten class to do it before." I assured her that I sub for all grade levels prek-12 at several schools and (as rarely as I sub specifically for kindergarten), I coincidently never had a class do "cooperative games". Mrs. T. just brushed me off, and I still to this day don't know what "cooperative games" is nor have I had any other kindergarten classes since then do it. 3. During the class' silent 'read-to-self' time, I kept the classroom lights on because it's better for their eyes and they can see their books better since the classroom would have been dark with very little natural light from the only window in the room. Mrs. T. walks in and firmly tells me "I always have the lights off during this time." Like I magically just knew her routine of things. 4. Before silent reading, I told a kid he could do work on his morning work first since he came to class late and didn't get to do it. And it was just 5 problems, so I figured, no big deal if he works on them real quick before reading... Mrs. T. sees the kid doing it and scolds him "You know this is for morning time only. Put it away and get your book out!" The poor kid tried to tell her that the sub (me) told him he could, but his words went in one ear and out the other. Then she went back into the hall. I told the boy it was my fault and I apologized to him for getting him in trouble. I didn't know it was that big of a deal. Is it just me, or does Mrs. Teacher have some...issues? Out of 8 schools and hundreds of teachers, she is the only one I can't stand.
