This is the very first project I use in my grade 9 drama classes, to get them warmed up and being creative.
It's quick (1 day rehearsal / 1 day presentations) and really uses limited props - just chairs and desks.
Since it's so fun and open, the students are actually excited to present, which really sets the mood and pace for the rest of the projects.
NOTE - for my older grade students who have taken drama before, I give them this INTRO project that has more parameters
TIP - To lessen the stress, I make it clear that I don't mark this project on anything BUT the rules of theatre (no back to audience / staying open etc.)
