Hey, how do I download it?
This is a warmer, and there is nothing to download. It's just an idea for your lesson, not a worksheet.
It is a filler my students like a lot.
You take a deck of small cards and write questions on them (different types and topics depending on the students' level). Then ask the student(s) to take some of them without looking at questions. They should try to answer their questions in turns. It can be a nice ice-breaker as well as it helps to know each other better.
