Not much time was spent on tattling. For older children who can write, maybe you could address these tattles the first few minutes of recess time. Perhaps missing a few minutes of recess would motivate some of them to reduce tattling. I think are great. I do, however have a theory about tattling especially at the second grade level.
Second graders seem to be the worst, or is it that they are the best tattlers in the world.
Sometimes it is something out of my control and I tell them I will look into it. I'm not convinced that squashing tattling completely is the right thing to do. I have come to the conclusion that at second grade something is going on developmentally. The children are highly aware of what you have set down as a rule and are becoming aware that so many children are not following the rule that you set up as a rule. Is it a rule if you don't get caught.
