How Long is my Toilet Roll?--A Simple Exercise in Mathematical Modelling
Johnston, Peter R.
International Journal of Mathematical Education in Science and Technology, v44 n6 p938-950 2013
The simple question of how much paper is left on my toilet roll is studied from a mathematical modelling perspective. As is typical with applied mathematics, models of increasing complexity are introduced and solved. Solutions produced at each step are compared with the solution from the previous step. This process exposes students to the typical stages of mathematical modelling via an example from everyday life. Two activities are suggested for students to complete, as well as several extensions to stimulate class discussion.
