For an in-class exercise using Lego or Duplo brick to illustrate the
economics of linear programming during a one-hour lecture, you should see an
article titled "Lego of my simplex" by Norman Pendegraft. It appeared in
the periodical OR/MS Today in February 1997 (OR = Operations Research; MS =
Management Sciences). You may see the article at: http://www.lionhrtpub.com/orms/orms-2-97/legomysimplex.html
