Preparation:Divide the students in to groups of four or five. Then ask the student to make the name for their ships for example with the names of animals, cities, movie stars or let them find their own favourite names.
Ask them to choose the Captain and the Shooter. The captain's duty is to memorize his ship's name, so he can reply if somebody call his ship's name. The shooter's duty is to memorize the names of the ships of 'their enemies', so he can shoot them by calling their ship's name.
Activity:Arrange all the captains in a circle, the ships' crews must line up behind their captains. The shooter is the last crew member in line.
