It sounds like you're on the right path. If from what you've said the
principal would like an 'art' activity to help illustrate team work then a
collaborative style might be interesting. TO DO:
1. Pre-label people from departments or grades if it is an elementary
level group so that you have a mix for a few groups. For example: 1 SCI, 1
SS, 1 Eng, 1 Math, 1 Music/Art and 1 PE teacher per group (if you want to
spend the time you can color code with self adhesive dots when they enter the
room then when its time call all red dots to one area etc.)
2. Set the same number of tables as you have groups with stuff that is of
abstract nature ... can be just found objects.
3. Plan a timer that would ring at say 3-5 minute intervals that expects
each group to move to the next table.
4. Explain the task by writing it out (this saves time) The task should be
to create something (you will need to describe the goal of your principal in
an abstract concept which should lead to some very interesting understandings
by the doing together).
5. Give 3-5 minutes for each team to prepare a reflection and then present
what they have created.
You would then prompt the presentations back to the original goal -
Good Luck - this assignment intrigues me so let me know what you decide to do
and how it works out. My email is: email@example.com - I am a Hs principal
and former art teacher.
