GEORGIA O'KEEFE is part of a series called "Artistic Masters", developed to introduce children to different artists. A simple step by step procedure allows even the non art teacher to deliver a successful lesson. This lesson includes the artist's bio, examples of their work/titles, a materials list, a completed sample of the activity and an easy to follow procedure.
The grade levels listed are only suggested grade levels; it depends on the class capabilities.
