CRUSH SCHOOL

I blog on Brain-Based Learning, Metacognition, EdTech, and Social-Emotional Learning. I am the author of the Crush School Series of Books, which help students understand how their brains process information and learn. I also wrote The Power of Three: How to Simplify Your Life to Amplify Your Personal and Professional Success, but be warned that it's meant for adults who want to thrive and are comfortable with four letter words.

Two Truths and a Lie: A Fun End-of-the-School-Year Activity Students Love

By the final weeks of school, students are thinking about summer, not content.

End of the year energy calls for activities that are quick, engaging, and interactive.

One of my favorites (and students ask for this one too!) is Two Truths and a Lie, classroom-style.

It's a simple priming for learning activity that requires zero to little prep, and gets students thinking, discussing, and debating within seconds.

Classroom infographic explaining the Two Truths and a Lie activity, where students identify a false statement among three options to strengthen retrieval practice, discussion, critical thinking, and student engagement.

How It Works

Present three statements related to your lesson—two truths and one lie.

Students identify the lie and discuss their resoning with a partner or group.

Then, reveal the answer and discuss any misconceptions.

Why It Works

Curiosity Grabs Attention

Students naturally want to know if they're right, so the mystery creates perfect conditions for engagement.

Retrieval Strengthens Learning

To find the lie, students must pull information from memory and active recall strengthens learning more than passive review.

Misconceptions Become Visible

Incorrect reasoning surfaces quickly, giving you an opportunity to address misunderstandings before they become long-term misconceptions.

Discussion Deepens Understanding

Students compare ideas, defend their answers, and challenge each other's thinking. In this way, the conversation is more valuable than the answer itself.

Classroom Examples

Science

  • Mercury is the closest planet to the Sun.

  • Venus is hotter than Mercury.

  • Venus has two moons.

Math

  • Probabilities can never be greater than 1.

  • A probability of 0 means an event is impossible.

  • A probability of 2 means an event is very likely.

ELA

  • Strong arguments use evidence.

  • Emotional appeals can influence readers.

  • Opinions alone are always strong evidence.

Social Studies

  • Rivers often influence settlement patterns.

  • Mountains can create barriers to movement.

  • Latitude determines a country's government type.

End-of-School-Year Pro Tips

  • Use common misconceptions for the lie

  • Let students debate before revealing the answer

  • Turn it into a team competition

  • Have students create their own rounds (own truths and lie)

  • Use it as a bell ringer, review activity, or discussion starter

Bottom Line

When summer is winning versus school at the end of the school year, students don't need more worksheets or packets.

They need activities that spark curiosity, encourage discussion, and get them actively involved.

Two Truths and a Lie does exactly that.

It's fast.

It’s fun.

It keeps students thinking right up until summer break.

Can you tell which of the three is a lie (but only a little one)?

I guess occasionally lying leads to learning that works.
