Reflection: Developing a Conceptual Understanding Capture-Recapture and an Intro to Probability - Section 2: Activity / Lesson: Capture Recapture


Counting - and our expanding definition of what that once-simple word means - is all about number sense.  My students and I are always surprised by what 100 beans actually looks like.  Try it.  Put 100 black beans in a pile, and see if it matches your intuition.

I include pictures here of what 100, 200, and 450 beans look like, because the piles are smaller in reality than what most of us imagine.  As I say to students today, "next time you eat half-cup of beans, you can tell everyone that you're eating 450 beans!"
