Students in my Upper Intermediate classes at Ritsumeikan Asia Pacific University wrote and performed role-playing scenarios as a part of classroom instruction. The constraints were as follows:
Role-playing scenes related to business and work
Work in groups of 3 - 4 people
Each member of the group must speak
Length: 1 - 2 minutes
Vocabulary: 5 -10 vocabulary words from a chapter in the textbook related to business and work
* Disclaimer: Some scenes in the video contain strong language or expletives. While strong, they are a part of natural English, and as such I chose not to sensor them.
