Lie Detector

Students get to know each other by guessing which statements are true about the other students in the class.

Level:  Any

Topic:  Icebreakers

Time:  40 minutes


  • Index cards (one for each student).
  • Prepare several statements about the teacher - one true and one false.
  • Write one set of statements on the board - one true and one false.  

For example:

1. Becki is 28 years old.

2. Becki has lived in Japan for 7 years.




Ask the students to look at the statements about you on the board. Explain that only one of the statements is true. Have the students guess which statement is true, #1 or #2, by raising their hands. Give the correct answer.


Ask the students to think of something unique or interesting about themselves to present to the class.


Give one index card to each student. Ask the students to write their name at the top of the card, and write sentences #1 and #2 under their name.

Give some time for students to write the two statements about themselves. Remind them that one statement is true and the other is not true.


Write the number “1” on one side of the board and the number “2” on the other side of the board.


Ask the students to stand up. Randomly call on a student to stand at the front and read his or her two sentences.  


Students who think #1 is true stand at the side of the room with the #1 written on the board. Students who think #2 is true stand at the other side.


The students who are wrong must sit down. The students who are correct continue to play.


Continue until each student has read his or her sentences. If there is only one student left standing and all the students haven't read their sentences, write his or her name on the board. Then, have all of the students stand up to play again.


The winner is the student with his or her name on the board. If there is more than one name on the board, then play a challenge round with the extra statements about you.


Intermediate Level:

  • Do steps #1-3 the same as above.

  • Assign groups of 3 to 4 people, and draw a scoreboard on the board. 

  • Randomly call on a student to stand up and read his or her two sentences.  

  • Any group can try to guess which sentence is true. The first group that is correct can get 1 point.

  • Give one minute for any group to ask a follow-up question. The first group to ask a relevant follow-up question gets 2 points.

  • Continue until each student has read his or her sentences. The group with the most points is the winner.
