I've been to several garage sales recently of retired teachers. At some of them I come across materials that are stamped with the school name "Property of __________ School." On principle, I do not buy any of these items. And I have been tempted to casually mention it to the teacher holding the sale. It just really, really bugs me because it indicates that they have taken school property and are selling it. Is it ever practice in your school to stamp items that you have spent personal money (and not been reimbursed) with a stamp that says it belongs to the school? I've been teaching for a while and at this point it is hard to keep track of what I bought with my money, what I bought with school funds, what was in the classroom when I got here, what was passed on by teachers who were leaving my grade level, etc. But when I pack up my things for the final time (many many years from now :haha I do intend to at least see if a school stamp is on it. And if it is, I'll leave it behind. Do you ever come across this? What do you think/do?
