I love this idea also! It does seem easy enough to teach to my upcoming 4th graders also! I love the idea of tying in some historical writing concepts and styles into my history and social studies lessons this year (especially being at a global awareness magnet school!). Teaching the students how to hold the brush and engage in the strokes seems interesting and engaging for the students, no matter the grade. I agree that this may be better geared towards middle or high school, especially for a visual arts course. I feel that it could also be tied in to language arts or creative writing classes as well. The videos are interesting to me as a teacher and I hope your lesson goes well!
