This was a drawing project I did with my mixed Grade 7 - 9 class when we were online a couple of years ago. I also taught this to my Grade 10 - 12 class- see their work HERE.
Students had to print a photo of someone of personal interest (actor, celebrity, musician, etc) or they could find an image in a magazine. They cut the photo in half and glued one half to paper.
Then they had to re-create the other half as accurately as they could, with a focus on shading and matching values.
I was super pleased with what they were able to achieve at home. I feel like some of them did even better on their own as there were far fewer distractions than in a classroom.
