I like what you wrote. I used Monart, too. I had all of my 1-7th gr classes
draw one LARGE object and transform it into another object. For younger kids
it could be a bee, then decide you don't want it and draw a butterfly right
on top, covering the entire bee, by putting the butterfly into a setting.
They had to color to cover the bee. We then drew a border and wrote about
what we did in the border.
All year I referenced this transformation, so they remembered they don't have
to start over, they can turn their "I messed up" into something else. What
happens when you start over? was my question all year. (You get tired of it,
you don't finish either artwork, and the class move on, and you have nothing)
