Description

What our Shortage and Surplus lesson plan includes

Lesson Objectives and Overview: Shortage and Surplus teaches students some key concepts about shortage and surplus and supply and demand, including the following: when supply is more than demand, this is a surplus and the value goes down; when the supply is less than the demand, this is a shortage and the value goes up; and when supply equals demand, this is equilibrium. At the end of the lesson, students will be able to define shortage, surplus, supply, demand, and equilibrium, will be able to explain the concepts of supply and demand, and will be able to apply their understanding of supply and demand to interpret data and graphs. This lesson is for students in 3rd grade and 4th grade.

Classroom Procedure

Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the yellow box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand. To prepare for this lesson ahead of time, you can make copies, cut out the Cookie Shortage/Surplus Activity cards, and create groups for the activity.

Options for Lesson

Included with this lesson is an “Options for Lesson” section that lists a number of suggestions for activities to add to the lesson or substitutions for the ones already in the lesson. One optional addition to the lesson is to connect shortages/surpluses to a historical context depending on what else they are learning. You can also have your students read current events to learn how supply and demand currently impact shortages and surpluses in the economy.

Teacher Notes

The teacher notes page includes a paragraph with additional guidelines and things to think about as you begin to plan your lesson. This page also includes lines that you can use to add your own notes as you’re preparing for this lesson.

SHORTAGE AND SURPLUS LESSON PLAN CONTENT PAGES

Supply and Demand

The Shortage and Surplus lesson plan includes two pages of content. The lesson begins by explaining that supply is the amount of an item or product that is available. Demand is the amount of the item or product that people want at a given price. When there is more supply than demand, we call it a surplus and the value goes down. When there is more demand than supply, we call it a shortage and the value goes up.

The lesson includes an example. In 1996, a popular toy called Tickle Me Elmo cost $30 in stores. Because it was popular, many people wanted to buy it for their children for Christmas. In other words, demand was high. It sold out in stores because supply was low, meaning there was a shortage. People started selling them for as much as $1000 because the value had gone up. The same item, Elmo, gained value because there was a shortage.

Reading Data

The next section of the lesson begins with a graph that shows supply and demand. As supply, or the amount of an item, goes up, the demand, or how much of it people want at that price, goes down. As supply goes down, demand goes up. When supply and demand are equal, we call it equilibrium. The left of the equilibrium point is where there’s a shortage of the project. In other words, there’s not enough of the product for everyone who wants it at that price. The right of the equilibrium point is where there’s a surplus of product. In other words, there’s more product than people who want it at that price.
