This summer I was fortunate enough to teach my own class, and I learned something really quickly with third graders...they love to tattle! That got old pretty fast so I made my very own tattle jar! When students would begin to tattle, I would simply divert them to the jar so they could write down their thoughts. Some days I would read the papers, other days I would simply toss them out. None the less, the students got their tattles out, and I didn't have to hear 100 a day! This idea would be great in any elementary classroom, or even at home with the kiddos!
I also posted this lovely sign by the jar, so they could decide if they were making good decisions.
