I originally came across this activity on Dave's ESL Cafe or FLTeach, which are also great resources for foreign language teaching activities. This is a GREAT activity for practicing commands in a fun way.
Write 4 or 5 commands for students. They can be weird and fun things but they have to be things that can be done inside the class at the moment (obviously they can't cause harm to anyone, etc.). Students will get in groups and come up with these commands to tell another group to do something. The other group (or a selected member of that group) will perform the action he, she, or they are commanded to do. Then, that group or group member, will give a command to the next group, etc. This activity can also be performed passing a ball around a circle with music like hot potato and when the music stops, the person with the ball will have to perform the command he/she chooses from a hat.
Examples: Put the vase of flowers on your head.
Stand on your right foot for 30 seconds.
Some commands that my students have used include the following:
• Open the door.
• Close the door.
• Walk towards the window.
• Dance the Macarena.
• Sing “La Bamba”
• Write your name on the board.
• Change desks with someone else.
• Raise your right hand.
• Jump on your left foot 5 times.
• Touch the shoulder of the person next to you.
