I've posted something pretty similar, but this continues to be an issue. My students (8th graders) simply do not respect my property! I've been through at least 200 pencils since January because they either do not return them, sharpen them until they're an inch long, or break them. Also, I've thrown away 8 dry erase markers (out of 32, all of which worked perfectly when I bought them a week ago) because students would either dry them out by coloring an entire dry erase board (the 9 by 13 inch ones a lot of teachers use for review games), stabbing the marker against the board and jamming the tip, or throwing the caps and losing them. Same thing with glue sticks. They throw and lose the caps, roll them all the way out and get them stuck, or stab scissors into them. And I've had one student break a pair of scissors. Some of these items were bought with instructional funds, while many were paid for out of pocket. It's hard to give consequences, because 99.99 percent of the time, they do it when I am not looking, or they must be doing it under their desks. If we didn't physically see it, we can't give a consequence at my school. I've tried "branding" my stuff with neon tape so I can easily recognize it, issuing automatic detentions for the first offense when I see a student mishandling my stuff, and immediate office referrals when they throw things. Nothing has worked. The students I suspect of doing it just say things like, "They cost like a dollar! Why are you so salty about it?" and it just makes me so angry that they have no respect for someone else's items.
