There is a game that my wife introduced me to that is called “Two Truths and a Lie”. You tell a group three statements about yourself, two truths and one lie. The more cunning and believable the better.
A bad example:
1. I am a teacher.
2. I am a guy.
3. I am a multi-millionaire.
The group would guess which is the lie and they would probably guess #3.
Here is a good example:
1. I have two degrees.
2. I went to two different colleges.
3. I have aspirations of skydiving someday.
A little sneakier, but it is still 3 that is false. I have no reason to jump out of a perfectly good airplane, but a group may not know that.
We were talking about verifying solutions to equations and I did this activity “Two truths and a Lie”. I used the game as a small group ice-breaker, giving them my personal example and after about 5 minutes, I let them loose with a set of 7 problems spread around the room. Here is an example:
I used a Google Form (distributed by QR code) to track responses. Here is a screenshot:
I will look at the data later to see how well they did. I had them work in partners, but report independently. They got a chance to talk about the process and argue over solutions, which was alright with me.
