A mingle is a short activity where learners walk around the classroom and talk to each other. An ice-breaker, where learners get to know each other, is a type of mingle.

Example
The learners are talking about attitudes to marriage. They prepare a question each and then mingle to ask others in the class what they think.

In the classroom
Mingle activities include class questionnaires, matching activities (finding your partner), group dictations, and role-plays.
