For the last few years, I've done a snowman collage lesson with fourth grade. It's a pretty simple lesson that I like to use just before the holidays. When complete, students are able to identify and create collages. They practice proper craftsmanship using scissors and glue. They are also introduced to mixed media. If they choose to add crayon detail, their collage becomes a mixed media project. Some students stuck with only collage, while others added light, shadows, and other small details in crayon. Here are a few samples.
