Who doesn’t love two truths and a lie? I picked up this idea from a fellow teacher. She doesn’t tweet but I want to give a shout out to Ms. Wood for this one. We started doing this during the comparing functions unit but you could do this with any unit. Imagine solving equations where two were solved correctly and one wasn’t. Great way to encourage students to defend their answers.
I do this in groups. The whole group has to agree what the lie is and be able to explain why. The lies are supposed to be based on common misconceptions, not some random wrong answer. The team presenting gets points if no one guesses correctly. Each guessing team writes on a whiteboard to commit to an answer. The team gets a point if the pick the correct lie. They get an additional point if they can accurately explain why it’s a lie.
Anytime you can make learning a game students love it. I love that we are sneaking critical thinking into the game.
Here are some examples of papers created. You decide what the lie is.
We have created these on individual whiteboards, scrap paper, and large chart paper. Whatever you have will work. I do recommend thicker markers if using paper. If not, the back of the room can’t see.
Please share topics you use two truths and a lie with. We would love to use them too.
