A good activity to start a lesson or revisit a topic which students may have forgotten about.
Teacher identifies a topic area, eg vocabulary associated with clothing.
Working alone, students note down as many words or phrases as they can remember.
After a specified time period (30 seconds/a minute), students turn to the person next to them, and exchange ideas to expand their list.
After a further 30 seconds/minute, the two students turn to form a four with a couple near them, and exchange further words or phrases.
