This is an ideal warm-up activity :) It should be played in two teams. Students from different teams sit next to each other so that they can check if they mention the forbidden words while explaining. You can give them 30 seconds or more if you like. The other members of the same group have to guess what word their colleague is describing, and if they guess it, they get a point. The team which has more points wins. I hope your students will like it!
