It was always Miss. Whether Mrs or Ms. Wouldn't have known if they were married or not when I was that young. My mom was a teacher, and most of the kids in the classes she subbed for probably didn't even know she was my mom. That's the way it should be. Just teach the subject matter.

Why would they have to mention their spouse in class. When I was growing up, we knew nothing about our teachers. They taught school and that was it. Just teach and leave everything else at home where it belongs.
