I called this Modigliani Lisa.
We called this one Mona Lester.
These are just a few of my favorite images from last year's Da Vinci Unit with the 7th graders.
This was a lesson in using the grid method. Students were given an image of the Mona Lisa with a grid drawn over it. They then attempted a square by square transfer of the lines within that square to a pre-gridded paper. They repeated the process on a piece of cardboard onto which they had drawn a grid. After transferring their lines they applied color (colored chalk) - inventively if they so chose.
