  • First Discussion: Collectively try to write out a rule that sorts pairs of numbers into coprime and not co-prime. Don’t feel obliged to use “mathematical” language: your goal is clarity and understanding. Conjecture boldly! Refine them in charity. Once you’ve come to consensus about your rule, you can play with it!
    • Now that you have a conjectured rule everyone is happy with, try to break it! Propose pairs of numbers and see whether they fit the definition well.
    • Can you make your rule shorter while saying the same thing?
    • How does your rule categorize 0.4 and 1.2?
  • Second Discussion: It’s always fun to compare our conjectures and ideas with mathematicians of yore. We participate in a great conversation across the millennia. You can play with Euclid’s definition of co-primality:
    • Euclid VII, Def. 12: Numbers co-prime are those which are measured by a unit alone as a common measure.
    • Does this say the same thing as your rule? Does it say it better? Worse? What are the trade-offs? What words in Euclid’s definition would you want to understand more?
