Hi! A noticeboard is something like this:

I�ve seen many variants of noticeboards, at university we had one that had some staples and pins for teachers to add news. Then, I used one which was rather simple to prepare: I covered some foam with cardboard and I used pins to add news, cartoons, and students� activities to it, so parents could see whar their children were doing every class (I updated the noticeboard daily)

Hope this helps you!
