Rough day in the teaching world

Today was just not a good day. I have been over tired and getting very little sleep. I had to teach a lesson today and needless to say it was by far the worst one yet. I was told what I was suppose to be teaching on and not given much room for freedom to deviate from her plans. I was suppose to review part of the novel with them and have the students complete a worksheet to follow. The students were not having any better of a day than I was because they did not want to cooperate. I trudged through the review with them and left them to finish their worksheet. Low and behold the worksheet took them a little over 20 minutes to complete in a 40 minute class period. Trying to think quickly on my feet I assigned them a note taking activity for the chapter coming up. Though I did manage to maintain control over the students it was not how I normally conduct my lessons. At the end of the day I was shown the need to be flexible and quick on my feet.
