I'm new to picture rubrics, but now that I've used my first one I can't believe I haven't been using them forever. I've found mine to be an invaluable tool, and I see possibilities for many others in my future.
The picture rubric below is one I created for my dental health unit. Since students would be creating a poster about their learning, I wanted them to have a standard and one that was easy to understand.
This rubric was our guide at the end of three separate lessons on brushing, flossing, and healthy eating. It touched on content, grammar, punctuation, capitalization, spelling, handwriting, details, and coloring. I loved that it made expectations explicit. Students could identify what made their work a 3, and they took more ownership. It took me out of the equation, because they pushed themselves. (That's what we call a game changer.)
