Quelle est l activite exercée par un tanneur

Bonjour! imagine you’re a teacher and your classroom is really cluttered. in a note to the janitor, tell him a few things that you don’t need and a few things to keep in your classroom. be sure to mention at least 7 total classroom objects. feel free to mention why you do or do not need those objects. (in french i assume but it does not say) (i would like this to be in french just in case you)
