Buddy is not popular with the other children because he always tells on them when he doesn't get his way. Telling is sometimes necessary, but it's not helpful if it only gets someone in trouble. This changes when his friend, Sarah, suggests he use the stop light as a model. The red light means to stop and think. The yellow light means to decide if telling will be helpful. The green light means to tell if this will help prevent harm or injury. It's important to know the difference between telling and tattling. This pack contains reproducible activities, a story book, posters, and a user's guide.
