Go for it. I teach 3rd through fifth, perspective drawing, and I go
veeeeery slow and teach a very narrow structured lesson to all my grades by
demonstration on a chart tablet. All those that don't understand get to learn
second hand at the chart tablet. I know this sounds mean, but with a class of
thirty, nobody knows what anybody is doing. I start with a farm scene, and
then do a city scene to increase their understanding. Most comic books
drawing books also incorporate city scenes, so I try to have them show a
super hero in their city scene.
