Georgia O'Keefe inspired flowers by Grade 1

This group of first graders has been by far one of the most challenging groups I've ever encountered.  They are a large and lively group.  With only two more art classes to go they really rose to the occasion with this project.  I'd like to think they wanted to redeem themselves with these watercolor flowers inspired by Georgia O'Keefe!
The students were given a square 12" x 12" sheet of white drawing paper, a box of watercolor paints, a paint brush and water cup. No pencils allowed for this lesson.  They were instructed to use an analogous color scheme of either warm or cool colors for their "huge" flower.  The students began in the center by painting a circle.   Some simple petal shapes were demonstrated then the students were instructed to begin painting around the center with a  contour line only of their petal.  They went around around and around until they hit the edges of their paper.  Once this step was complete they began making washes of their chosen color scheme to loosely fill in the petal shapes with color.  Backgrounds of green were used to add the final touch. There were a few students who stepped out of the box and did not use neighboring colors and their flowers were every bit as beautiful.  I think Georgia O'Keefe would be proud!  I know I am!
