6th grade students are creating Op Art using cones and spheres. First, they traced circles with a roll of tape and created the curved lunes inside each creating a sphere. Using a sharpie, color every other section, like you are creating a checker board. Next, using a ruler, create eight equal triangles. Create curved lines in the form of a "smiley face" line in every other triangle. Then create curved lines in the form of a "frown face" line in the leftover triangles. Use four colors to fill in every other triangle. Here is a glimpse of artists in the works!
