I have hanging signs "sculptors, artchitects and painters" in one classroom.
In my other school we cannot hang things from the ceiling because of the
motion detector, so we taped the table labels (the other teacher I worked with
wanted colored numbers so we did that instead of artists names or jobs) to the
center of the table with clear packing tape. Oh we laminated the number first.
I also use colored dots to label my seating and to go with my job chart...I
tape those to the table too.
