Share and Replace Board

Have some plastic folders with a poster in stating- 
‘PLACE YOUR RESOURCE HERE’
Next to those plastic folders- another poster stating- 
‘PHOTOCOPY THE RESOURCE YOU WANT- REPLACE IT WITH ANOTHER?’

Idea is that staff take a resource sheet that has been left there and simply replace it with another?
It really does work!

Try it?

Variations:

Use it in your dept?
Use it for revision?
Use it as an activity?
