I go in about 6:30 each morning and have 1st period as conference time. Then I teach 6 math courses in a row, 2nd thru 7th, with a short lunch break followed by Channel 1 time after 5th period. We get out at 2:35pm and I usually leave around 3:30. So far, I leave just about every day with achy feet and back, and other times with a headache to accompany the pain. My voice is also starting to fade and not from yelling; I haven't had to really get onto my kids just yet, but it's all the non-stop talking I do all day that's wearing me out... Any ideas on how to become more efficient? If I'm not teaching, I'm monitoring student work and walking around the classroom...but something has to change if I'm going to make it through the year.
