This is a little twist on the dissecting and coloring technique. If at the end you shade the corners of each shape you make, you get a softer and more sophisticated abstraction.
1. Students draw a vase that takes up most of the drawing paper. To help with making a symmetrical shape, they may fold scrap paper in half, draw, cut and trace. When the vase is done, a few simple flowers are added on top.
2. Using a ruler, the drawing is dissected by drawing about 7 or 8 rotating lines all the way across the paper. The goal is to have a lot of medium size shapes to color.
3. All of the shapes inside the vase and flowers are colored with warm colors: red, orange and yellow. All of the shapes on the outside are colored with cool colors: blue, green and purple. The students are to color all the shapes lightly first, and then chose one corner that gets shaded darker with the same color.
