I wasn't sure if it was a 7th grade thing (I hadn't noticed them in other classes) or if it was something new. I asked where they got them. One girl admitted that she made some, so apparently it's a middle school crafty thing. Most of the girls had multiple ones (it looked a bit like the '80's were back) while the boys only wore one (on each wrist).
I like to see that the kids make things. At least they do some work. Today's history assignment...not so much.
