I loathed art that looked all the same. I encouraged kids to be creative and normally presented a set of materials and had the kids dig in. Eventually, one skilled crafter would create a great idea and in a spirit of sharing, they would help those less able, through lack of ability or disability, to put together a plan. Those were blessed moments.
Everyone took a photo of their own art, and put it on their web page. Of course, some were better artists than photographers, but I digress!
My favourite activity was one created by my Core French teacher. They all had to create an alien, determine its characteristics, build it in plasticene, and then I helped the kids take a photograph. We made an iMovie of the resulting set of photos.
Tye Dye day was a fun one. Sponsored by the parent council, we all took turns.
