I walked into my advisory one day to find these things occurring:
The day before, one of my students had mentioned planking and another asked what the word meant. We really have no curriculum or structure for advisory, so I decided we should learn about planking that day. I pulled up the YouTube video from the Australian news station and we discussed how the plank position is actually a yoga position as well. Then we went back to our scheduled activity (I think we were talking about integrity).
Then the next day this happened. I laughed so hard when I saw my students planking on my desks! I immediately took pictures. My 8th grade boys are pretty funny.
