 Activity for teaching passive voice, relay tennis game. An easy to set up activity that's a lot of fun and can be used with a variety of tenses. Set the class up into two teams and have them in lines facing each other. Give a vocabulary prompt to start, such as rice, and students have to create a passive voice sentence using the patterns from your lesson. The game works by having a student at the front of the line create a sentence, then the person opposite them in the other team must say something else. Work your way up the line back and forth until someone either repeats what has already been said or can't think of anything new. The opposing team gets awarded a point when you restart the game with a new prompt from where it left off.
