A perpetual dilemma of schooling is how to help students develop skills needed for everyday life, including the work world. Quantitative literacy, also called numeracy, involves an ability to apply essential mathematics skills to authentic or near-authentic tasks. Carefully planned classroom activities can help students develop these important skills. One type of quantitative literacy that merits classroom attention is financial literacy. In this article, the authors describe a financial literacy lesson where two middle-grades classes draw on real-world resources to develop an overview for opening a small business. The students selected their own business, researched and calculated costs involved in opening and running the business, created advertising plans, logos, and slogans, and brainstormed ways to acquire the required start-up capital. Skills in quantitative literacy and small-business planning can yield economic success. (Contains 4 figures and 8 online resources.)
