Manners Matter: Always Say Thank You (Blue) Poster Set 1 is a 5 poster set reminding students when to say Thank You. The posters include saying Thank you for something given, for help, for a kind act, and for a compliment. This is the first of many Manners Matter poster sets to come! Teaching manners will increase cooperation among students as it decreases discipline issues. It is my goal to bring manners back to as many students as I can. This fun poster set is one of my many manners activities including bulletin board sets and games. I hope you enjoy this motivational poster set!
