Chess Instruction (Felt Board)

I am about to start teaching chess lessons at a volunteer after school program, and I am looking to get one of those Magnetic chess boards that pin to the wall. The only problem is I don't know what they are called and am having a hard time locating one. Can anyone help? I will post a picture if possible

It's proper name is a demonstration board, I think.

Don't get the magnetic version, get the slot loaded one instead.  In addition, please know that they're cheaper at wholesalechess.com

Thank you both :)

already got the slot loaded. thanks for you help guys :)

chessmessbess incidentally (f.y.i.) I stated never go with the magnetic demo board is because the pieces a) slow one down in teaching as you attempt to move them off a square onto another or off the demo board. In addition, b) the magnet in time does fall off its glue, this issue is of no matter with the slot loaded demo board.  The slot loaded version also affords the chess teacher/coach the ability to move pieces quickly especially when your period with the students/team is short.

I am glad you purchased it! Best of luck.

Thank you very much for explaining that. I trusted your judgement, but now I understand, as do others, what you meant :)
