We have the lesson Camouflage the squares.
the prep work involves the teacher searching sources for nicely varied pen
and ink works and cutting them into bits. I made irregular pieces about 1
x1 inch. then I make sure they can not be easily re assembled by breaking
the original into 4 shoe boxes that circulate the room.
You can do any variation. We have student select 2-3 bits, glue stick them
down randomly on a 5x5 or 6x6 square of paper. First with pencil than late
with dip or 21 century pens. Develop an artwork that first camouflages the
edges/merges the edges into a larger artwork. "jump started" by the pieces.
Student usually just let the picture develop.
Of course the mean art teacher wants 4 or more types of textures and 4 or
more ways to create tone dots stipple hatching cross hatching etc. *I have
them do an art lab practicing marks before we do this unit. The students
really value these art works and every one seems to get something out of
them.
