4th Grade "Op Art"

4th grader artists looked at the artwork of "Op" artists Bridgey Riley and Victor Vasarely. Th ese artists used science and math to try and create the optical illusion of three-dimensions on a two-dimensional surface. Typically their artwork either receded (fell back) or advanced (came towards). After creating our drawings we reviewed the color wheel and used complementart colors to really make our drawings pop. Finally we added some value (light to dark shading) to our drawings with colored pencils to further create the illusion of a curved 3-D surface.
I found the idea for this lesson here.
