Fourth Grade Op-Art

First the fourth graders drew convex and concave lines inside triangular columns, then traced with black marker.
 We then talked about value and the lightness and darkness of a color and how to achieve that using a colored pencil. They then chose two colored pencils and began adding value to the convex and concave sections.
 Finally they chose a marker of the same colors and used long convex or concave lines to fill in the areas between the colored pencils.
