Math Curiosity: Ulam Spiral
Students will generate an Ulam Spiral, highlight the primes, and note what patterns they see.
You can read more about this math curiosity on Wikipedia.
- Students arrange the first 100 (or so) integers into a spiral.
- They will highlight (or circle) only the primes in their spiral, looking for patterns.
- Finally, they will either extend their spiral or try to create a new shape or spiral and look for patterns.
- A huge, pre-generated Ulam spiral In case your students cannot form the spiral, or want to work with a huge one. Note: The direction of this spiral is opposite of the one in the video, but the patterns will be the same.
