This is the rubric that I use for their HALF/HALF portrait project in art class, but really it'll work with ANY pencil drawing project.
It includes a chart at the top used for their mini critique that happens the week their project is due.
Everyone puts their artwork on the tables.
Then they do a "GHOST WALK" where they walk around, not commenting or talking at all. When I say stop, they complete the chart with specific feedback for the drawing they're in front of.
It's really neat to see - they actually use the comments to fix up their work before it's evaluated!
The rubric at the bottom is what I use to mark them on the project.
Also in my shop!
