Jim ran the second part of the HS OR program. He began by sharing his world wide experiences as part of “Statisticians without borders” He is currently working on reducing infant mortality in displaced person camps in the Sudan.
He introduced them to linear programming with a hands on lego example. This activity is critical to helping students concretize the concepts of decision variables, objectives, and constraints (the number of lego pieces). He also demonstrated shadow by offering to sell one more Lego piece for 2 dollars. He then introduced a more complex example involving skateboard production and engaged them in discovering the corner point principle. He also showed why an integer constraint makes the problem more difficult.
