Here is a Spy Game I edited for this lesson. (I posted this earlier but then noticed some slides I hadn't fixed the first time and am reposting updated version now). I first learned about this game from my Korean co-teachers :). I don't know who originally invented it, but kids LOVE it haha. They always beg to play it again.
How to play: Every student gets a secret card and they have to walk around the classroom asking each other, "What will you do this summer?" and answering, "I will..." The objective is to find all the students who are on the same team as them. The catch though is that there are a few "spy" students who lie and pretend to be on their team. Students don't get to see other students' cards, so they only discover the spies at the end when they run up to the teacher to check if they got their whole team or not. Usually we like to reward teams who have successfully found all of their members with a stamp or sticker. If they have a spy only the spy gets the sticker.
Cards: Are in the ppt on the last two slides. They need to be printed, cut-out and folded. Only pass out what you need based on how many students are in your class. Spy number can be adjusted.
