I can’t believe I had never heard of Vi Hart or seen any of her videos until this week – makes me feel like the proverbial cave-dweller. I now know that Vi is Internet-famous for her math videos on YouTube – many of which feature doodling to show and explain mathematical concepts. Math requires thinking and doodling is very visual, so you can’t get much more visual thinking than Vi’s series of Doodling in Math Class. What’s the point of doodling and math you might ask? In Vi’s words, “*to show that simple doodle games can lead to mathematical results so cool and beautiful that they’re famous.*” So, sit down and strap yourself in for a wild, frenetic doodle-fest sampling of Vi’s doogling math lessons.
