Social skills are a great thing to go over in guidance class as it helps to improve the interactions between all students in your school, thus preventing some issues from ever developing. A pre/post test would be a great place to start, in addition to a few lessons I have used from TPT as a social skills series for k-5 classes. Depending on the time you have for guidance, you can combine 2 of these lessons each day.
