Working Wall that shows samples of all the work done throughout the unit. Great way to display student progress over a longer period of time. This type of board allows classroom occupants and visitors to appreciate the whole learning process.
Nameless papers drive me crzay! Easy and adorable. No Name board. Clip papers that don't have names on them to the board and have students go check there instead of spending your time trying to figure out who they belong to!
My teacher uses a Noise Meter similar to this one. The Noise Meter is a cool way to remind students the correct noise level that they should be using! You just use the paper clip and move it to the appropriate noise level the students should be using.
