This one is a personal favourite. One student is a two way interpreter, and two other students have a conversation via the interpreter. Below are example instructions to set up and run the activity, and some scenarios to use.
This activity is great for accuracy of language and meaning, and I also love that it brings the learners’ first language (their ‘L1’) into the classroom.
I’d suggest giving the ‘interpreter’ role to stronger or more confident students to begin with, before rotating later.
