This is a fun activity to practice either "tu, usted, or ustedes" commands! Students have a series of 15 tasks in a command form to complete with their partner (things like switch your seat with your partner, make a paper airplane). The first group to complete all 15 tasks wins! The students have a lot of fun with this activity and it gets away from more dull fill-in-the-bank commands. I have included this activity in 3 different forms: tu, usted, and ustedes command forms, to suit the type of command you are practicing. I give the "winners" a bonus point or a piece of candy!
*Beware, if you do this at the beginnig of class the students will want to play with their paper airplane the rest of it!
