This recent magazine article features range lights in classroom activity for teachers:

"Practical applications such as the range light activity can connect with students on many levels, from the pracitical to the theoretical...Being able to apply basic mathematical concepts to real-life situations changes the way mathematics is taught in schools."

"Both range lights and channel markers use line segments to approximate curves...Aerial views of the paths taken by runners on a marathon course or paths taken by race cars on a sinuous race course provide other examples of line segments that create paths between two boundary curves."    Click to read the whole article.
