Make a list on the board with some personal information (English name, name in home country, major, hometown, birthday, etc.)
Also list a few interesting questions for students to answer (What is the one thing that makes you unique? What do you expect to learn in this class? What makes you angry? Where did you went and what did you do during the recent holiday?)
Get the students to write their answers on a piece of paper.
Collect the papers and mix them up. One at a time, call out the name of each student and encourage them to come up to the front and get them to tell the class about themselves based on the information they wrote down.
For more advanced students, don't be afraid to keep them in front of the class to ask few more questions!
