Stars and Factors: A Math Doodle

Mar 7, 2023 | Hinsdale

We've all had the experience of sitting in math class, looking at a blank sheet of graph paper, feeling the desire to doodle. Usually, doodling would be a distraction from learning about math—but what if we could doodle in a way that strengthened our understanding?

In this fun video, mathematician and musician Vi Hart introduces a fun game of doodling stars with different numbers of points. As the video unfolds, Vi Hart describes how using numbers with different factors to generate the points of a star changes the ways you can draw the star, leading to all sorts of fun combinations!

As you follow along with the video, take note of the factors for each kind of star. Can you identify the patterns in the ways of drawing stars? Which kinds of stars do you like drawing most?
