Technically, this is snow day #7 for us. (Snow day #6 was on a day of conferences and teachers had to reschedule the conferences on their own time.) All of our snow days have happened since January 1. If you also include the regular days off, like President's Day and MLK Day, we have had a very inconsistent schedule in 2018. The graphic below shows this inconsistency. An Blue box with an X means NO SCHOOL; this was a planned day off from school. Red means "Snow Day" and Yellow means 2 hour delay or early dismissal. When we have a 2 hour delay or early dismissal, the classes that were scheduled to meet at the beginning of the day or the end of the day don't happen.
Since January 1, I have seen my period A class for a total of 28 one-hour class periods. My period F class I have seen a total of 30 one-hour class periods. I have lost 6 hours of instructional time for period A and 4 hours of instructional time for period F.
That translates into one less week of time for review. For the past eight or nine years, my students have reviewed one chapter a day for 12 consecutive school days. Now they will need to review 2 or 3 chapters each time we meet. The fact that on Monday I had one of my "A" students ask me, "What is the median, again?" has me very, very concerned.
I know that there are other AP teachers that get zapped by snow days in the Northeast and rush to complete the curriculum and review. If you have any thoughts on minimalist reviews, I would love to hear from you.
