I had a station with all of the supplies needed. (Picture to come) The students used a tracer for the body with their choice of 6 different colors, strip to make the eyeballs, irises (6 colors choices again), and teeth.
For the dimensions of the tracer, you can look to the tutorial I found (link found above). I am just showing you the materials that I had set out for the students. They used the strips to cut their own circles for the eyeballs and irises. Then they cut triangles half way through on the smaller white strip to make the teeth.
I had so much fun with these, I can't stop making them. Thank goodness for "Stumble Upon".
