In a face-to-face classroom: Read each statement aloud. If you agree, move to one side of the room; if you disagree, move to the other. Talk with your group—why do you feel that way?
-
In an online classroom: Use polls, emojis, or the chat box in your online platform to show your opinion. Then, join the conversation as a group or in breakout rooms.
-
For independent learners: Read each statement and think about your opinion. Then say your answer out loud and explain your reason, as if you’re talking to a classmate.
