At the beginning of each year, I like to do self portraits with the kids to see how much they remember from last year, how much they know if they're new, and see how much they've improved since the last time we created them. They're just so cute too!
We start out by doing a "before" that they do without any instruction or reminders. Then, we do an "after" with me! We do kind of a directed drawing, where I go over what shapes to use, and where to put the features and hair.
After that, we trace them with Sharpie markers, and color them in.
