I use this Forced Topic game to help students generate topics for opinion based speeches. It is very helpful in getting diverse topics from the students as they are forced to have at least an "agree" or "disagree" opinion for each statement. I created this because I was going to scream if I heard one more "marijuana should be legalized" speech! There are 58 slides with one statement per slide. I usually don't get through all the statements in one 50 minute class as I allow for the students to discuss the statements.
The game's instructions explain it best: "In this game, you will discover what you believe about certain topics and issues. Statements will be read aloud to you as well as printed on the screen. Move to the right side of the room if you agree with the statement and move to the left side of the room if you disagree with the statement. You are FORCED to choose a side, you cannot stand in the middle of the room and say “I don’t know what I think” or “I don’t care about this issue.” Be prepared to support your decision for agreeing or disagreeing with the statement. Because you are discovering your opinion, there is no right or wrong answer. There is only what you believe. Some will agree with you, others won’t. Note: These statements do not reflect the beliefs of any particular person, they are just general statements created for the purpose of this activity."
