Crayola Creativity Central One of my favorite tools from my childhood, Crayola continues to inspire me. This website offers lesson plan ideas for a variety of subjects, especially for visual arts.
The Art Institute of Chicago This school was actually my topic choice when I was college searching but unfortunately due to financial reasons I could not attend. However, they do provide art lesson plans on their site.
Davis School Arts Magazine With ideas submitted from various art teachers there's much variety in these plans and since its a magazine there's always something new posted often!
Teachers.net I liked this site because it had lesson plans, projects and also an art teachers forum. I like the interaction provided with forums
Theteacherscorner.net this website provided lesson with a large age and ability range, from elementary to adult lessons. I liked this variety.
