Instead, it seemed a reasonable (and exciting) leap to have them paint blocks as structures as seen over at let the children play (then daisy-chain yourself right to the source irresistible ideas for play based learning).
Andrea and I have always wanted these and once I took a look at how all the artwork has stacked up along the walls so far this year, I immediately thought of the spiraling forest walk building designed by Hundertwasser in Darmstadt. Using the iPad, we showed the children the images of this building along with Hundertwasser paintings and they got right to work.
The blocks aren't all done, a couple of children have been out with assorted fever/coughs. We are really looking forward to seeing these blocks as part of a greater landscape.
