In third grade we read the story Tease Monster by Julia Cook. This story does a great job explaining that teasing is a part of everyone's life, but there is teasing that takes away from our life & teasing that adds to our life. We join "one-of-a-kind" as he figures out which teasing is good-natured and which teasing is hurtful.
Afterword we discussed how we can tell the difference and tips to consider before we tease. I used many personal examples to show students how very different our feelings can be when it comes to teasing.
