Thursday. Eighth grade math. Seventh period.
When Ms. M planned these two weeks that she'd be out, she found a unit that would take two weeks to complete (including unit test). She kept the topics similar for the seventh and eighth grades, although they wouldn't be the same.
The seventh graders had learned about circumference and area of circles. The eighth graders had done the volume of cylinders.
As a sub, I don't usually spend a whole period going over notes and problems and examples. (I usually introduce an assignment, answer some questions, and let them work.) So, by the end of the day on Thursday, I was worn out.
I had taught the same lesson all day. They started with questions reviewing what they had done the previous class session. Then I went over the answers, starting by writing down the formula for the volume of a cylinder.
"Shouldn't that be squared?" a student asked.
Instead of writing down the formula for the area of a circle, I had written down the formula for the circumference. (Something the seventh graders had done the previous day, but something none of the eighth grade classes had done on this day.)
I wrote down the formula three different times, only getting it right on the third try.
Yup, I was tired. And loopy.
I had to shake it off and get my brain in the game. This was material that was new to them, so I had to get it right.
I did. Eventually. After a shaky start.
It's a good thing I don't get too flustered when I make mistakes in front of them. I just own that I made an oops and continue on. (And I thanked the student who caught my mistake. What a disaster if I had continued on with the wrong formula.)
By the time I get used to teaching them all day, my two week assignment will be over.
