Tattling: Should I Tell or Grow Thick Skin? Power Point presentation on telling, tattling, when to seek help, when to ignore, bullying, mean kids, and how to tell the difference. This presentation has helped my students understand that some problems are bigger than others. It helps them understand that some kids are really "meanies" rather than "bullies" and how they can grow "Thick Skin" instead of tattling on every little problem they have. I have used this with my 4th graders, but it would work best for grades 3-5.
