Choose children's books that emphasize the buying and selling of goods (physical objects that are bought and sold) and the trading of money for services (actions done or steps taken for a second party). For example, picture books such as "Boom Town", in which a child decides to make money by selling pies, or "Pancakes, Pancakes", a book in which a boy encounters many goods and services in the goal of making pancakes can both demonstrate these ideas and clearly differentiate between them.
Consumers (those who use or buy the goods and services) and producers (those who create the goods or provide services) can also be demonstrated by using "Boom Town" and "Pancakes, Pancakes", as well as any other children's text that focus on buying, selling, consuming or producing a product or service.
Natural resources (those that come from nature, such as oil, wood, etc.) as well as human resources (workers) and capital resources (machines that aid with labor) can be discussed through children's literature. The picture book "Why Should I Save Water?" can help children understand what natural resources are, and the book "Drylongso," a story about a farming family, can help children to understand the interplay between natural resources, human resources and capital resources.
Production refers to the creation of a product (or output) by an organization. Many books can include this topic, as many include some element of production. In particular, "Pancakes, Pancakes" can clearly demonstrate what production means and how it meets society needs.
