i use a lesson i got from the text: Understanding Art. in the first chapter
there is a lesson on the elements. i have the students draw a continuous
line, fold the paper so there are 8 equal spaces and then go through the
steps with them. it is good. then i have them do a lesson i call creative
line design where they have a set of given lines and have to make something
out of it, one picture, not a bunch of little ones. the results are always
fabulous! i do this at the 6th grade level.
