Trade and Depending on Others

Aligned to C3.D2.Eco.2 — C3 Framework for Social Studies State Standards.

What this lesson teaches

No community makes everything it needs. Trade means giving one thing to get another. Communities depend on each other, so they trade goods and services back and forth.

Worked example

A town near the ocean might trade fish to a farm town, and the farm town trades back corn and wheat — each gets what it cannot make itself.

Practice questions

  1. What does trade mean?
  2. Why do communities need to trade with each other?
  3. Name one thing your community might get from far away.

El Comercio y Depender de Otros

Ninguna comunidad produce todo lo que necesita. Comerciar significa dar una cosa para obtener otra. Las comunidades dependen unas de otras, así que intercambian bienes y servicios entre sí.

Ejemplo: Un pueblo cerca del mar podría intercambiar pescado con un pueblo de granjas, y el pueblo de granjas devuelve maíz y trigo — cada uno obtiene lo que no puede producir por sí mismo.
