Student teacher dealing with tattling....can you recommend a book or some ideas?

[Laura F]

I am student teaching and my second graders are HUGE tattlers! They tell on every little thing other people do. I have decided, along with the classroom teacher, to make "Tattling Teddy". We are going to have a teddy bear next to a box and if the students need to tell us something they write it and put it in the box. Teddy will "tell" us what the student's put in their every night. Does anyone have a good book title on this topic or have any helpful adivce they think would cut down on all the tattling in the classroom? Thanks in advance! :-)
