Students need to have lots of opportunities to share their opinions based on text. In this lesson, the teacher will read the story, Jack and the Beanstalk, multiple times before the students create their opinion. The detailed process of modeling this skill, an example of a completed student's work, and a video of the lesson are provided.

This game helps students to understand the concepts of changing supply, changing demand, and equilibrium price, as the price of bags of ice changes after a hurricane has swept through a community.

In this module, students learn about market equilibrium.

Prices for most goods and services are determined in markets by what economists call supply and demand. This module uses a fictitious chocolate market to help students better understand how supply and demand work together to determine prices.

NOTE: This module assumes that your students already understand the economic concepts of demand and supply. If your students do not have a deep understanding of demand and supply, please assign the EconLowdown Demand and Supply modules first.

Think like an engineer and build an aqueduct in this interactive activity from the NOVA: "Secrets of Lost Empires: Roman Bath" Web site.

This website offers a very simple yet helpful description and example of the interaction of supply and demand, and what will happen to price and quantity when one or both of your supply and demand curves shift. This would be a good place to start if you are just beginning a study on supply and demand.

Principles of Macroeconomics 2e covers the scope and sequence of most introductory economics courses. The text includes many current examples, which are handled in a politically equitable way. The outcome is a balanced approach to the theory and application of economics concepts. The second edition has been thoroughly revised to increase clarity, update data and current event impacts, and incorporate the feedback from many reviewers and adopters. Changes made in Principles of Macroeconomics 2e are described in the preface and the transition guide to help instructors transition to the second edition. The first edition of Principles of Macroeconomics by OpenStax is available in web view here.
