Time out!!! Change of plans. I dismissed the 57% who had been in class on Monday and sent them to lunch. Then, I taught the lesson on one sample t-tests to the 43% that had missed class. When we reconvened from lunch all students had time to work on the problem set on one sample inference for means. I am fortunate that I work in a school that allows me the flexibility to work with the students in this way. However, with more snow in the forecast, I am nervous about students learning all the content needed before AP exams start. Right now, we have 5 days on the schedule to review for the exam. This is about half or one-third of the time I have had in previous years.
