I am currently teaching facial proportions and was tired of the same lesson I do every year. I found this on Pintrest from the site: http://www.princetonol.com/groups/iad/lessons/SubPlans/subelem.htm I think the kids enjoyed them and found them to be pretty successful. I would teach it again.
We started with a oval template and traced it onto a horizontal 12 x 18" drawing paper. They then focused on getting the correct facial proportions. After the face was finished, we then erased the oval from one ear to the other. I asked them to use their names as the subject matter. They could use block or bubble letters to fill in for hair. Then in the negative space they used pattern to fill it in and give it more interest. We then used colored pencil to trace over our pencil lines. Some students asked to use more than one color others stuck with just one color.
