Icebreakers are activities used to help students get to know each other at the beginning of a class. They establish rapport and help students feel comfortable sharing and practicing language skills together. The document describes three icebreaker activities: 1) More Than Name Tags, where students fill out info about themselves and ask each other questions, 2) String Get-to-Know-You, where students pass a ball of string while answering questions to create a "web" of connections, and 3) Find Someone Who, an information gap activity where students find classmates matching descriptions.
