Summary

Let’s find how the diameter and circumference of famous circles are related.

  1. First, students make a guess about how many times they'd need to go *across* a circle in order to equal the distance *around*.
  2. Next, they'll measure across printouts of famous circles.
  3. Then, using string, they'll measure around.
  4. Now, students will look for a relationship between the diameter and circumference.
  5. We reveal that the relationship is π.
  6. I explain a bit more about π.
