This is one of my favorite art projects. We read the book, Snowmen at Night, and discussed the shading and how snowmen don't just look white when it is dark outside. The students were instructed to include a snowman, a moon, and their snowman had to be doing an activity. Great work, 4th Graders!
The idea (completely not my own) came from a blog of a 6th grade class on Pinterest from here: http://afaithfulattempt.blogspot.com/search?updated-max=2010-12-04T12:40:00-07:00&max-results=7.
