1 Teacher Notes Activity at a Glance Subject: Social Studies Subject Area: Economics Category: Production, Distribution, and Consumption Supply and Demand Curves and Market Price Equilibrium Activity 1 Exploring Demand and Supply Schedules Topic: Supply and Demand Curves and Market Price Equilibrium Grade Level: Prerequisites: Students should be familiar with concepts of supply and demand for products and goods and also the concept of a marketplace. Total Teaching Time: 120 Minutes Materials TI-83 Plus, TI-83 Plus Silver Edition Student Handouts: Demand Schedule, Supply Schedule Activity Overview Tip Describe to the class that the activity will be in two parts. First, using the handout titled Demand Schedule each student will complete an individual demand schedule for the price of a candy bar. Second, using the handout titled Supply Schedule students will create a supply schedule for paper airplanes. After completing the schedules the class will combine all their individual schedules and create, with the teacher, demand and supply schedules for the whole class. They will graph the schedules and discuss the properties of the demand curve and the supply curve. They will discuss how price affects the quantity demanded and supplied. The whole class will discuss what factors may cause changes in the demand and supply curves. It will be worthwhile to select a product that the students can relate to in their own spending habits. I used candy bars for the demand activity and paper airplanes for the supply activity. Directions for Demand Schedule Before the Activity Begins Make sure each student has a TI-83 Plus and that the lists and graphs are cleared. It may be easier for some students to read the numbers if they are rounded to 2 decimal places. This can be done by setting the mode to 2 decimal

2 2 Economics Lesson: Supply and Demand Curves and Market Price Equilibrium places. Press z on the calculator and highlight the number 2 and press Í. The screen should look like the following: Warm-up Activity Begin the activity by exploring with the students how price affects how much of a product they buy. Have them give concrete examples. During the Activity Distribute the Demand Schedule work sheet to the students. Make sure students understand that they should be realistic on how many candy bars they would purchase at a certain price. Monitor the students progress to insure that students are completing their work. It may be necessary to start the students with an example of what you would purchase at the first few prices. When students have finished their work sheet, explain that they have completed an individual demand schedule. Now they will report as a class and generate a demand schedule for the whole class as if the entire class represented the marketplace. 2 Discuss the parallels to this model in the real world where many individuals make up the marketplace. 2 Discuss why the demand schedule for the entire marketplace for a good or service may be different than for an individual. Collecting the data for the entire class may be done in various ways. Once completed, the class should write the demand schedule for the class in the table on the student work sheet and graph it on the TI-83 Plus. By tracing on the graph, students should explore how quantity demanded changes as price changes. From this, students should be able to formulate the law of demand. Students should discuss why demand behaves the way it does and should comment on the effect of product substitution on demand as well as the effect of the income on demand. Students should now investigate how an increase or decrease in demand affects the demand curve. They can do this on the TI-83 Plus by adding and then subtracting to the quantity demanded. Instructions are given on the work sheet. After the Activity Lead the class in a discussion on the factors that lead to a change in demand for a good or service causing the curve to shift. Factors to guide discussion could

3 Activity 1- Exploring Demand and Supply Schedules 3 include: income changes; population and demographic changes; preferences and tastes; consumer expectations about price; and the prices of substitute goods. Directions for Supply Schedule Warm-up Activity Begin this part of the activity by exploring with the students by asking how price affects how much of a product is produced. Have them give concrete examples. During the Activity Distribute the Supply Schedule work sheet to the students. Make sure students understand that they should be realistic about how much they would supply at a certain price. Monitor the students progress to insure that students are completing their work. It may be necessary to start the students with an example of what you would supply at the first few prices. When students have finished their work sheet, explain that they have completed an individual supply schedule. Now they will report as a class and generate a supply schedule for the whole class as if the entire class represented the marketplace. 2 Discuss the parallels between this model and the real world where many individual businesses make up the marketplace. 2 Discuss why the supply schedule for the entire marketplace for goods or services may be different than for an individual. Collecting the data for the entire class may be done in various ways. Once completed, the class should write the supply schedule for the class in the table on the student work sheet and graph it on the TI-83 Plus. By tracing on the graph, students can explore how quantity supplied changes as price changes. From this, students should be able to formulate the law of supply. Students should discuss why the law of supply works the way it does, and comment on the effects of revenue and profit. Students should now investigate how an increase or decrease in supply affects the supply curve. They can do this on the TI-83 Plus by adding and then subtracting to the quantity supplied. Instructions are given on the work sheet. After the Activity Lead the class in a discussion of the factors that lead to changes in supply and the reasons why the supply curve might shift. Factors to guide the discussion could include: cost changes (including cost of component parts, labor, transportation); number of businesses; technology changes; environmental changes; and the prices of related goods.

4 Student Work Sheet Demand Schedule Name: Date: In the following chart place the number of candy bars you would purchase in an average week if the price charged is as indicated in the table. Individual Demand Schedule Price (cents) Quantity Purchased After everyone in the class has completed the above, combine everyone's individual schedule to compile a demand schedule for the entire class. Class Demand Schedule Price (cents) Quantity Purchased 1. How does the class schedule parallel the marketplace? 2. Why might the demand schedule be different for an individual when compared to the marketplace? 3. Construct a graph of the demand schedule for the class on the TI-83 Plus graphing calculator. Press then select 1:Edit by either pressing 1 or by highlighting the 1 with the cursor and pressing Í.
