Tomorrow is the half day before Thanksgiving.  Most half days seem like a waste and I know that is also felt by other teachers and is also the expectations of students.  So what do you do on a half day?  We normally have 84 minute blocks, and the half day reduces the time down to around 40 minutes.  I know this is normal time for period scheduling, but for me, it is like the blink of an eye.  How can you fill the time, what can you do to still be productive, or is it ok to have a “free” day.  What do others do.  I plan on filling my day tomorrow with a short quiz and some demos.
