Another workshop theme last year at work during workshops, as we discussed where we wanted students to go/where they were at and what 'foundation' to build our teaching on was The Three Little Pigs.
We had straws...
Pigs in a Blanket (kind of morbid...I guess that makes us the wolves?).
And then all our papers were on red acme brick with the info for the meeting for building a solid foundation. Get it? Huh? Do ya? Whatever...it makes planning workshops so much more fun. You could also serve rice crispie treat squares as bricks....but it didn't really go with the 'theme' b/c we needed something to tie it all together.
