Colorful cities created by kindergarten and first grade. The buildings were scraped on with a cardboard scraper in primary colors. When the buildings were finished, black paint was put out and the road was scraped along the bottom. We let the paintings dry and in the next class added the outline and windows. To make the outline students used the edge of a smaller piece of cardboard to print (not scrape) straight lines around the buildings. When the outlining was finished, white paint and a brush was used to add the windows. I really like the look of these. They were easy enough for the little ones, and the kids really liked making them.
