Though I've had these whiteboards for at least 15 years, I haven't used them all that much in middle school....yes, I have pulled them out from time to time, but they weren't a part of my regular activities...I don't really know why. I used them much more often when I taught elementary school.
Anyway, since re-taping them, I have kept them out on my counter, in sight, and maybe that's why I think of them more often. Today, students completed a Footloose activity for algebraic expressions, and of course, they all finished at different times. So, as they finished, I had students sit at an empty group of desks, with the whiteboards, and work on Order of Operations flashcards (I am loving these too, by the way - this is the first year I've had them, and they make for great, quick, differentiated practice). I hadn't planned to have them do this whiteboard work, but the cards and the whiteboards caught my eye, and the kids were perfectly happy to grab a whiteboard and marker and get started:-)
Just wanted to share:-)
