What to know Scarcity exists when people want more of something than is available. Because resources are limited, people, businesses, and communities must make choices. Trade lets people exchange what they have for what they need or value. A good economic explanation names the scarce resource, the choice, and the trade-off.

What to know A good is a physical item; a service is work done for someone. Buyers create demand and sellers provide supply. When demand rises while supply stays limited, prices often rise; when supply is plentiful, prices may fall. Money makes exchange easier than finding a perfect barter match.

Money, Saving, and Spending Learning goal: Describe useful characteristics of money and reasons people save.
What to know Money is portable, durable, divisible, recognizable, and generally accepted for exchange. Saving sets money aside for a future need or goal; spending uses it now. A plan helps people compare needs, wants, price, and future goals. North American places use different currencies: U.S. dollars, Canadian dollars, Mexican pesos, and several Caribbean currencies.

Global Trade Connects Us Learning goal: Trace how trade connects resources, producers, transportation, sellers, and consumers.
What to know Imports are goods and services brought into a country; exports are sent to another country. Places trade because climates, skills, technology, and natural resources differ. Transportation and communication connect producers and consumers across long distances. Trade creates choices and interdependence: people rely on work and resources from many places.
