This lesson comes from CHF (formerly The Canadian Hunger Foundation). The site contains an excellent lesson plan that can be used as an introduction to Standard of Living, the Human Development Index, and the disparity among the world's nations in these standards.
Students, in groups of 4 or 5, play a card game which provides them with different scenarios that either increase or decrease their overall well being. This provides a great opening into a discussion of disparities among the different nations and societies of the world.
The lesson plan includes black line masters for student handouts, background information for teachers, and an evaluation rubric. This lesson could be used when examining Canada's economic, political, and developmental role in the world. Student worksheets are also available in French.
