This Annenberg Interactives site asks the question, “How do numbers affect everyday decisions?” The several sections cover topics as wide-ranging as statistics, using math when decorating a room, ratios encountered in cooking, and figuring out the best deal when buying on credit. Every high school student should be conversant in all of these areas of math. One interesting topic explains why math is the universal language shared by all regardless of culture, religion, gender, or time in history. When you get the question from your students, “Why do I need to learn this stuff?”, you’ll find some good answers here.
