I'm telling!

I don't know about you, but if I hear one more kid whine, "I'm telling!" I think I may pull my hair out.  My class is full of tattlers reporters.  I searched high and low and finally found the book of my dreams, A Bad Case of Tattle Tongue.  It's a story of a young boy who reports everything he sees and drives everyone around him crazy.  No one wants to play with him or sit with him.  The Tattle Prince comes to visit him while he is sleeping and teaches him the difference between tattling and informing an adult of something important. The Tattle Prince has 4 rules:
1.  Be a Danger Ranger- It's not tattling if someone could get hurt.
2.  Be a Problem Solver- solve your own problems.
3.  Now or Later?  Some problems can be solved later, some must be solved now.
My favorite rule
4. MYOB- Mind Your Own Business

Here's the chart we made to help us remember the tattle rules so we don't come down with tattle tongue.  So far, it's helped my friends out tremendously.  We have had to refer to our chart, but our tattles are definitely slowing down.  How do you prevent tattling?
