Baseball has been a business since the 1860s when organised teams first started paying their players. Since then, baseball has become a huge business enterprise earning billions of dollars each year. In this unit, students will be introduced to basic economic concepts such as goods and services, supply and demand, and competition. Each lesson includes an activity that will allow students to practice recognising these concepts as they relate to professional baseball. Students will also have the opportunity to practice their math skills as they calculate prices of various ballpark items.
