Strange Days Indeed

My 3rd period elective class has been disrupted today due to CMAS testing.  7th and 8th graders have a modified schedule, so they don't go to their 3rd period classes. They go to their 1st period classes instead.  On the other hand, 6th graders have a regular schedule so they do go to 3rd period.  This means I have 3 sixth graders in my 3rd period and none of the other students showed up.  Actually, this is ok.  I will not introduce any new material in todays class.
