The student will decide on a composition and draw this out in pencil on the canvas board. Remember the focus is on the geometric. Robert Swains painting of a triangle is also shaped like a triangle. Please take advantage of the library and library suggestion list included exposing your child to the paintings of Frank Stella and Piet Mondrian at least. If the Internet is more convenient, use your favorite search engine to look up these artists by name.
Second step is to decide on their color placement.
Have the students do a paint swatch, so they are familiar with the colors they'll be working with. Simply paint a stripe of each color on a white index card or other white paper. This is a great reference tool. The hardest part of this project is being patient and staying within your pencil lines. Younger children will enjoy the process better if you create some simple stencils of their chosen shapes.
