Printmaking

The picture above is from a lesson with the focus of printmaking. First, you take a styrofoam sheet and create a design with an object that can make a dent. I used a pencil. After your design is made, cover it with paint and place it face down on construction paper. 
This activity can be useful when learning about printmaking. It is simple and would only take one class period for students to complete. As a teacher, you could introduce various elements of design, such as line or shape, and have them make prints of those.
