Polar Clock isn’t precisely a Meyerian[1] What Can You Do With This? creature.  But I do think the Polar Clock falls in the same genus as WCYDWT because it could inspire some pretty cool mathematical investigations.

If you’re a Georgia math teacher, check out standards from Math II, specifically the properties-of-circles stuff under MM2G3.

I ask y’all, what mathy questions does the Polar Clock inspire? Leave ’em in the comments.


[1] As I understand it, Dan Meyer’s WCYDWT requires that the problem have a hook anyone can guess at, that the math scaffolding can slowly be lowered, and that the photo/video/hologram/whatever look good. I got this based on my reading of
