This lesson came about because of an abundance of construction paper. Students tore the paper into long strips and used glue to collage them along the bottom of a larger paper. They added sailboats as they chose to and colored the sky with oil pastels.
I tied it in to artists who painted ships like Winslow Homer, Thomas Birch, and Claude-Joseph Vernet. We live near the ocean so many of the students had been on a sailboat but I also showed them pictures of sailboats for reference.
