Styrofoam prints are always a sure-fire hit with kids. They're pretty easy to make as well; you just need to set up some effective printing stations.
For these prints created by Grade 2 students, they first drew a winter scene
into a piece of styrofoam with a dull pencil.
Once the drawing was finished, using a foam brush, students painted over the styro with white acrylic paint. Place a piece of coloured paper on top (choose something darker for contrast) and rub firmly with a brayer, a rolling pin or simply your hand. Peel off carefully and students will be amazed!
