In reference to creating your own art in front of the students: I don't.
I teach k-5 classes. My experience tells me if I get too complicated with
my own drawings and samples on the board, the children compain that they
can't do it that way and give up without trying. I show completed samples
of student art work and then my samples. They aren't interested in me
completing the project, they just want me to quite drawing and talking so
they can get to work. Karen
