I am having some trouble with students who steal or break or damage the art
supplies. I have had two substitutes this year and when I returned, the
room was a terrible mess. Rulers were bent, erasers crumbled, colored
pencils broken... I feel like taking everything away from the students. I
can't punish specific children because I never know who did it. My
students are 7th, 8th, and 9th graders who seem to be quite irresponsible.
Does anyone have experience or advice in dealing with this problem?
