Procedure:
Start with a demonstration with your JTE by showing your I have/I have never sentences. Check for comprehension after you read/say your sentences. Then, ask students to vote which sentence is true. Reveal your answer and award points for those who guessed it right.
After the demonstration, give the students 5 to 10 minutes (depending on the proficiency level of your students) to write their sentences. The worksheet is designed for 3 pairs of I have / I have never sentences. Remind them that one statement should be true and the other one false. Make sure to go around and help them with their sentences.
Divide the class into groups of 3 students. Make them decide who goes first. Explain that during their turn, they have to say a pair of I have/I have never sentences and ask their classmates which one is true. They should also award points for those who guessed right. There's a box in the worksheet so they can tally their own points.
When all groups are done, you can ask the students who won in their groups. You can also ask one or two of your students to come to the front to share their I have/I have never sentences for a whole class guessing game.
