Day 1: Introduce the artist, discuss the artwork (describe, analyze, interpret, judge), students draw 1-3 buildings with pencil on black construction paper to be traced with bottled glue. Ask students to leave a "pinky-width" between shapes so the glue does turn into a big blob.
Day 2: Use construction paper crayons to color in all the shapes.
I'm a sucker for construction paper crayons on black paper and the added texture from the glue makes it more interesting. The kids really enjoy this project too. If a student missed the first class, I had them draw their lines in shapes with a white crayon then follow the same procedure for adding color as if the white crayon were glue.
