From my past educational and teaching experiences, here are a few different approaches to ice breakers that I utilize in my classes:
1) Note Card--on a 4 x 6 index card, have the students answer a series of questions on the card (e.g. why are you taking this class?, what are your career aspirations?, what are your hobbies?, etc.) in order to get to know your students a bit better. You can go around the class and have students answer the questions, but make sure to collect the cards at the end of the class to be able to reference.
2) Circle Introductions--go around in a circle (just as the module indicates) and ask the student to introduce herself, say what brought them to that particular class, a hobby or unique quality, or any other question that you find fitting (this is ideal for smaller classes).
3) Name in a Bucket--have the students put their names on a piece of paper and crumple it up and put all of the names in a bucket. Have each student draw a random name out of the bucket and after all of the names have been picked, have the student pair up with the student on the piece of paper and learn three facts about them. After a designated amount of time have the student introduce their partner to the class.
