This is a great, active opening week activity for any classroom!
You get to learn some things about your students, and they get to learn some things about each other, and about you (you get to participate, too!) This document includes a list of statements, and if it is true for that student, the student stands up and shouts, "That's Me!". They can look around and see who enjoys the same kinds of things. Examples include:
I like to sing or play an instrument
I like animals
I like comic books
