Hey Jasmine.
We did a summer program with middle school kids which worked out quite well.
We split the kids up into group of 5-6. The number is arbitrary, depending on
how many
kids and support you have.

Of course, we started with our safety talk, them followed with this task:

The activity: As a team, the kids were to prepare the horse for inspection.
In our activity the horse became the client/student and the kids became the
supporting
staff. The kids became a team, roll playing these different psitions: the
leader, the
councilor, the teacher, the parent(s), and the horse groomer(s).

Only the leader could talk to everyone, and was to make sure the task was done
"right".
The councilor and parent(s) could talk only to the leader, and only about safety
issues.
They each were to make notes (provided w/ clip board & paper), which are
reviewed after
inspection.
The groomer(s) were not allowed to talk.
Consequence was applied if any talking occurred that was out of roll, or
inappropriate.

During processing afterward, we asked them each to discribe which roll they were
most
comfortable with and which they were least comfortable with.

It was amazing the appreciation the gleaned from playing the different rolls.
