I found a coloring sheet from Crayola. http://www.crayola.com/free-coloring-pages/print/st-basils-cathedral-moscow-coloring-page/ This served as a starting place to draw our own pictures. We have drawn cityscapes in the past and so after we got our first building in place, they were able to easily continue the picture with more buildings. By adding the onion tops, it gives the illusion that this is really a drawing of St. Basil's. I asked them to rub the chalk into the blue construction paper. They drew with oil pastels and then went back and refreshed the lines after they chalked. Some of the students added shadows and highlights which really helps the pictures look more dimensional.
They added stars or fireworks with oil pastel after they finished the buildings. I love the bright bold colors that pop. I often will hold up a picture and compliment a student on feature of their work. I find that as one student has success, that it buoys the others on to trying to make their pictures better.
