Students in grades 4-6 have been working on Rotational Symmetry drawings for the past three class periods. This is one of the many math concepts that directly connects to the visual arts. I love teaching this lesson because the results are stunning, the kids feel confident about their work, and they want to work hard for the final product (which is sometimes a challenge for the 6th graders). I have the students create a simple drawing on 1/8 of their circle, then teach them how to "transfer" their drawing into all 8 parts of their circle by putting pencil led on the back of the piece of paper and tracing over the original drawing 8 times. We also discuss some techniques of using colored pencils, like graduated coloring, shading, and blending colors together.
Step 1: Divide circle, Draw design onto separate 1/8th
Step 2: Fill backside of design piece with pencil lead
Step 3: Trace over design into each piece on the circle,
pressing hard to transfer the lead from the back onto the paper.
