The students in my fifth grade class, were asked to make 4 prints. On print #1, they were asked to use watercolors over their print (you can see these in my previous post). On their second print, they were asked to use oil pastels. I wanted them to see how different materials/media can change the look of a picture. I encouraged them to fill space and try blending. I found it easier to get them to fill space than to blend colors. Like always, there is one brave sole who will try it out. And once they see success, they will experiment some themselves.
