Have you ever had those moments when a student says something that you just can’t believe they said? Have you ever asked a student, “Why would you do that”? or, “Don’t you know that” or the classic, “What were you thinking”? Then you probably have some students who could use a little direct teaching of the hidden rules. These are a set of habits and expectations that society creates and expects everyone to learn vicariously. When it becomes obvious that some kids don’t’ do this, we need direct instruction. This social story sets out explaining what hidden rules are and why they are important to know. It is a basic introduction with some examples of what not to say to others – mostly in regard to appearance. It also touches on some hidden rules with the teacher. We always use perspective taking to help our students better understand their peers. And of course, we give options of what to say instead. At the end of this story are additional resources. This topic should be a continual conversation in teaching students with social deficits and the story suggests that students identify a ”safe person” who can help them with any questions regarding hidden rules.
