I play this game with students at the beginning of the year to get to know them a little better and to start breaking the ice in my classroom, but they BEG to play it all year long!
The rules are easy: just gather the kids in one area (I have them line up down the middle of the room, but you can just clump them together anywhere, really). Then you read a Would You Rather question (I like to read the "Would You Rather" part rather dramatically with a not very good British accent) and point to one area of the room for the first option and a different area of the room for the second option. Once students choose a side (and they know they MUST, no matter how difficult!) I call on a few from each side to defend their decision. After that they come back to the middle for the next question.
An added bonus to this activity is that it boosts critical thinking skills and listening/speaking skills! I just thought of this (imagine that), but questions from specific content areas could be used as well for review- example: would you rather live in the desert or the arctic? Would you rather be a mammal or a fish? Would you rather go back in time to the 1800's or 1900's? You could also use it for character education: would you rather tell someone the truth and hurt their feelings or tell them a lie to spare their feelings? Would you rather be nice to your enemy or mean to your friend?
This freebie is a list of about 50 of my favorite Would You Rather questions.
