I would like my art classroom to be a cultural experience for my students, as well as a spark for their own investigation into diverse peoples and cultures. I believe that learning about diversity at an early age can help foster respect for "outsider" peers the students may encounter. For this particular lesson in an elementary class room, the students would be looking at Australian Aboriginal paintings. The focus would be on shape and pattern in conjunction with a discussion of The Dreaming and Aboriginal culture. Students would be asked to select an animal from the out back, break its body down into shapes (ex. circle for its head, triangle body, rectangle body etc.). After drawing these shapes on different colored sheets of construction paper, the students would cut them out, and assemble the bodies on a larger sheet of paper. A discussion of Aboriginal use of patterning would follow and students would be asked to embellish each part of their animal using simple markings (dots, circles, lines, etc.). Finally, students would work in groups to create a story about their animals' experiences in the dreaming. This lesson includes some geography, "Where is Australia? Northern or Southern hemisphere?" As well and some geometry in dealing with shapes. And of course some social studies (as any art lesson should).

I'm a big fan of pre-assessments. I think its good to have some understanding of your students' knowledge base before you begin a unit or project. For this lesson, I would do a verbal assessment of my students' knowledge about Australia and Aboriginal art at the end of the class period before I began the project. Older students might write what they know on exit passes. These would help me plan my presentation on Australia and give me some idea of what I needed to cover.
After the presentation, I'd go over daily goals the students should try to meet. This will help me assess their progress and investment in the task, as well as their on task behavior as the project progresses. Students would begin their projects.
The final project serves as its own summative assessment. I would develop two rubrics, one that sums up their on task behavior (non graded, this would be just to help me get an idea of who needs more help in the classroom and how I need to tailor my instruction for them) and a final project rubric.
http://rubistar.4teachers.org/ is a good resource for creating rubrics. You can select categories in different subjects or create your own. Even if it doesn't have the specifics you're thinking of, it gives you a good idea of what to look for and how to break evaluation up.
Finally, I would ask students to keep a working/developmental portfolio in their sketchbook. This would include their notes, sketches, project plans, graded rubrics, feedback, and worksheets. This serves as another formative assessment that will help me see which students are progressing and which students need differentiated instruction. Separately, students would keep a best of work portfolio to document their final, graded projects (no self respecting art teacher lets her students store their masterpieces haphazardly).
