Class Opener – Day 34 – Dolphin Tales

It’s Wednesday, and that means it’s Student Choice for today’s opener.  This week’s ideas comes from Katie, who loves dolphines.  An article from Discovery claims that dolphins may be math geniuses, using the subtraction of echos from their built-in sonar to determine location and depth.  There are some links here to the geometric distributions we have been studying in class.

Before sharing the article, I let the video below play, which features a pod of dolphins caught on GoPro camera. There’s a “wow” moment here, as students realize how organized and detailed the pod is with their travels.

More great student sharing next week!
