I love the books "I Can't Believe You Said That!" by Julia Cook and "Being Frank" by Donna Earnhardt but have struggled to find meaningful examples for my students to practice with. This product is a set of task cards with 12 different situations/thoughts for students to sort into: "Keep it in your head", "Say it out loud", and "Filter it". There is also a set of blank cards that you can either add your own scenarios to or have your students create their own with.
