Standards for Stringing Together Supply and Demand: A Tactile Approach to Graphing

Standard: 4

Name: Markets

The interaction between buyers and sellers determines the market price and allocates scarce goods and services. Buyers and sellers make decisions based, in part, on market prices.

• K-5: Elementary school students learn that markets determine the prices of goods and how people change their behavior when prices change.
• 6-8: In middle school, students are formally introduced to the concepts of supply and demand and what is meant by an equilibrium price. They are presented with a situation where the market price is not in equilibrium and learn how equilibrium is restored. Finally, they discover that a change in the price of one good can impact the market for another good.
• 9-12: In high school, students learn about shortages and surpluses, and how supply and demand changes impact the market price. Finally, the concept of the price elasticity of demand is introduced.Benchmark Students will know that: Students will use this knowledge to: 4.E.1 A market exists whenever buyers and sellers exchange goods or services.Identify items they purchased in online marketplaces and at a local market (e.g., grocery store or school fair) and describe the differences between digital and physical markets. 4.E.2 A price is what people pay when they buy a good or service, and what they receive when they sell a good or service.Identify one of their favorite items purchased with their own money and what price they paid, or what they charged when working for others (e.g., chores around the house, yard work for a neighbor). 4.E.3 Higher prices for a good or service provide incentives for buyers to purchase less of that good or service, and for producers to make or sell more of it. Lower prices for a good or service provide incentives for buyers to purchase more of that good or service, and for producers to make or sell less of it.Provide an example of a good that they did not purchase (or their parents or caregivers would not purchase for them) because it was too expensive and predict how low the price would have to drop before they would be able to buy it. Decide if they would take out the garbage, babysit a sibling, or do some other chore for $1 and, if not, decide at what price they would be willing to do the chore.E: ELEMENTARY STUDENTS National Content Standards in K–12 Economics | 20 Standard 4: Markets
