Cardinality Cartography: A Computational Artifact for Exploring Number Patterns

In this video I explore Ulam's Spiral and Number Mandala's as computational artifacts students can use to explore patterns in numbers. I wrote an app to generate Number Mandalas here: http://ideonexus.github.io/Explorable-Explanations/math/numbermandala/ I wrote a book full of ideas for teaching Computer Science, check it out: https://nostarch.com/coding-classroom
