For my class, I gave each student a paper Japanese flag and a paper US flag. As we scrolled through the powerpoint, students lifted which flag they thought the practice on the slide came from. They were allowed to choose Japan, USA, both or neither (although you'll notice that most of the questions are both, because of the purpose of the game). After revealing the answer, I spoke a little about the topic. I have written some notes in the presentation that you are welcome to use as well.
