While surfing for lessons on Visual Literacy, I came across this very
thorough lesson plan for Mithila Painting: Folk Art of India
http://ias.berkeley.edu/orias/Mithila/OverviewMithila.htm
Lesson includes overview/objectives/essential questions - background
information - resources - image library as well as day-to-day lessons.
This lesson is suitable for middle school and up. You could substitute
tempera paints for the medium - instead of watercolors.
This unit was written by Kay Corcoran, 6th grade teacher at Del Mar
Middle School in Tiburon, California.
