This is a great 10-15 minute activity to get to know your students on the first or second day of school!
You go through the "stand up if..." list and the students that the statement applies to stand up. Then EVERYONE sits back down. The teacher reads the next statement and the students that statement applies to stand up, then they all sit down and so on.
My students loved this the first day! They get to see what they have in common with their peers.
