Very clever and great way to visually teach mathematics
Rainy - which is VERY unusual for this time of year - we are normally very windy and dusty in southern NM(Las Cruces)
Really liked your post.
Reminded me an ah -ha moment in geometry regarding lines, curves, bounds etc. being made up of a infinite number of dots(points)
Or a curve being made up of an infinite number short lines - curvilinear, etc...
Great memories of learning this back in my early schooling - many thanks again for posting
