Summary
Let’s find how the diameter and circumference of famous circles are related.
- First, students make a guess about how many times they'd need to go *across* a circle in order to equal the distance *around*.
- Next, they'll measure across printouts of famous circles.
- Then, using string, they'll measure around.
- Now, students will look for a relationship between the diameter and circumference.
- We reveal that the relationship is π.
- I explain a bit more about π.
