Use the skills in a new task

Make four small boxes for Markets Public Choices and Common Resources, one for each lesson: Demand Is Not Just Wanting; Supply and Production Conditions; Public Investment Has Trade-Offs; Shared Resources and Stewardship. In each box, choose one supplied card and explain its match using the notes. Compare two of your cards: what makes their matches different? You may write, draw or explain your answers aloud. Use the lesson cards; you do not need a purchase, interview, personal record or trip. For the adult helping: keep the fictional examples and historical notes distinct; these short cards do not tell every detail about a person or place.

Work on paper or in your own document. Explain the choices you made.

  • Choose one supplied card from each lesson: Demand Is Not Just Wanting; Supply and Production Conditions; Public Investment Has Trade-Offs; Shared Resources and Stewardship.
  • Use the notes to name each match and explain its clue.
  • Compare two cards and say or show how their clues differ.
  • Keep the events and details as written; do not make up a quotation or new event.
  • With an adult, name one question the cards do not answer.
Compare with a model response

Demand Is Not Just Wanting: The card says: “Fictional table lists purchases possible at $2, $3 and $4.” That matches Demand schedule. Demand schedule is quantities buyers are willing and able to buy at different prices. Compare: The card says: “Fictional buyers would buy six notebooks at $2 each.” That matches Quantity demanded. Quantity demanded is the quantity willing and able to be purchased at one stated price. Supply and Production Conditions: The card says: “Fictional bakery receives more flour deliveries.” That matches Input availability. Input availability is access to materials or other production resources. Compare: The card says: “Fictional bakery pays more for flour.” That matches Production cost. Production cost is resources or money used to produce an item. Public Investment Has Trade-Offs: The card says: “Fictional park plan lists construction expenses.” That matches Initial cost. Initial cost is resources required to start or build the project. Compare: The card says: “Fictional park plan includes annual repairs.” That matches Maintenance. Maintenance is resources needed to keep the project functioning. Shared Resources and Stewardship: The card says: “Fictional reservoir plan caps daily withdrawals.” That matches Use limit. Use limit is a stated restriction on resource use. Compare: The card says: “Fictional team records river-water measurements.” That matches Monitoring. Monitoring is checking and recording the resource’s condition. Adult checking note: This model uses the supplied lesson cards and notes. It does not describe every person, community or place. Answering a new question would need a matching source or a new observation.

A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
