Stacked Shapes - Op Art

These "Stacked Shapes" were done on the LAST day of school, this past June. The kids had already packed their things, and the classroom was bare....but no worries, still a little time for just ONE MORE art lesson! (I try not to pick favorites, can't help it this time....It's the Cheese-Its!)Big thanks to Deborah Brooks at Arapahoe Ridge Elementary for submitting this lesson plan to Artsonia, and she thanks Linda Welling for showing her the lesson first.Step1: Choose 2 shapes, then draw them vertically in an AB pattern.
Step 2: Add a circle to the inside of each shape.
Step 3: Draw a shadow line on the outside edge of each shape.
Step 4: Draw a shadow line inside the circle, on the "opposite" side of where the first shadow line was drawn. (This indicates a hole in the shape.)
Step 5: Color & add a background.The results.......

Big thanks to Flamson Middle School kids in Sra. Velasco's 7th grade class!
