I'm so happy with the results of this project. My 2nd graders were fascinated learning about Vincent Van Gogh, and had a great time imitating swirly skies by using our multicolor crayons (the kind I made by melting crayons into a muffin tin) for layers of texture rubbings.
When the skies were complete, the kids each tore a couple of 8"x18" construction paper in half horizontally, and used the torn pieces to create 2 layers of a landscape. Then we discussed "near and far", and how things close up look bigger, and far away look smaller (kind of a primary lesson in perspective). They cut scraps of paper to make houses, trees, and more, making big ones for the front layer, medium ones in the middle, and small ones in the distance. We used crayons and markers to add details when the glue was dry. I was impressed at how well the kids got the concept, even adding in some roads and sidewalks, narrowing as they recede. Aren't they terrific?
