#ELTwhiteboard is not just for writing 

Well, today is something a bit different. I thought I’d show you a picture of my whiteboard near the start of class. 
The students were answering the question on the main part of the board. We came upon one of the trickiest sets of loanword-versus-usage problems. Also there were a couple of issues with “(a pair of) THINGs” that is really a pluralised single item. 

Luckily I had some really with me. I would have loved to pull the socket of the wall, too. 
I almost always have Print Tack (or くつきむし [kutsukimushi] in Japanese) with me. It’s what I use for reading/picture gallery tasks, too.
Do you use the whiteboard or blackboard for anything a bit different?
