Math in the Real World

Many economics and personal finance concepts overlap with math curriculum, but economics and personal finance teachers are not trained to teach complex calculations and formulas, and math teachers may not focus on the personal finance and economic applications. A new CEE resource, Math in the Real World, brings together the expertise of math teachers and economics teachers to create interdisciplinary lessons that teach important personal finance and economic concepts in the context of math lessons.
