Students line up at the back and the front of the classroom. Each student is given a question. If they get it right, they go to the back of the line. If they get it wrong, they must sit down. The winning team is the one with the most players left in the line at the end of the game (which is whenever you get sick of playing, or when there are no more students in one of the lines). Can also be played with the whole class standing. Students stay standing if they get the words right or sit down if they make a mistake. Last student standing wins. To make it more difficult, ask for the spelling and the meaning in Japanese.
