We had a lot of destruction of property this year in my room. As we collected textbooks to turn in at the end of school, I found that kids had crossed out their names and written in different class names in the front cover. There has also been scribbling done all over the classroom--on name tags, on coat hook labels, supply labels, desks, etc. A lot of the supplies have also been ruined, such as markers being ripped in half, things being cut up with scissors. You get the idea. I don't know how to stop this from happening next year. I keep a good eye on my kids and do a lot of walking around the classroom and checking in while they're working. I'm never at my desk. I feel like I'm a pretty good observer of student behaviors. I really don't know how this even happened or if it was just one student or quite a few. Any ideas on how I can put a stop to this next year? The kids just don't seem to have much pride in taking care of the supplies and their lack of respect for the materials just makes me sick. Talking to them about it doesn't really seem to help.
