Advanced level students will catch on to this game quickly. You can make it tougher by providing definitions in English for your vocabulary. You provide each student with a definition and they must come up with the appropriate keyword.
I recommend that you play this game after you’ve spent a significant amount of time teaching new vocabulary. I usually teach my students and ask them to study keywords and definitions for homework. Then I use ‘Survivor’ as a warm-up activity for next class.
