This is a short one and can be adapted to various levels. I usually use it to practice the phrases: We all/both, One of us, None of use, All of us/Both of us etc.
- Put the learners in pairs or groups of three. Explain they will have a time limit (say 3 minutes) to ask each other questions and find out what they have in common. You could stipulate that they MUST find one unique thing about each other and one common thing.
- You may need to review question forms briefly for lower levels. Start the timer. Circle and make notes as the learners are speaking.
- Have the groups report back to the class. Alternatively, have them write a few sentences first (or as home work) and then report (using the phrases above).
For 1-1 lessons this still works well. Just get the learner to talk about a colleague/friend they know to include the “all of us/none of us” in addition to “both of us/neither of us”.
