This is an in-class writing assignment that I give AFTER studying "Romeo and Juliet"
It requires students to write two paragraphs - looking at two different characters (one major / one minor) and how they develop in the story / their role in the play.
There's also reminders for them before writing, which includes tips on paragraph structure.
Also included is a rubric that makes marking really easy for you.
TIP - it's a great alternative to a full essay OR you could easily have them pick their strongest paragraph and develop it into a full essay afterwards.
