Unit review questions
1. Use the economic notes. A teacher provides instruction. Which choice best fits?
Need a hint?
  • Look at the task: growing crops or animals, making products, helping a customer or removing a resource from the ground.
  • Find the note for Service. Check which words in this card match it.
2. Use the economic notes. Delivery vans use connected streets. Which choice best fits?
Need a hint?
  • Find the transport feature: a cargo port, train tracks, a road or a constructed water passage.
  • Find the note for Road. Check which words in this card match it.
3. Use the economic notes. A fictional county’s grower sells within that county. Which choice best fits?
Need a hint?
  • Start with the named area. Track whether goods enter it, leave it, are sold within it or pass through without a sale there.
  • Find the note for Local trade. Check which words in this card match it.
4. Use the economic notes. Fictional loads: boat eighty boxes, truck thirty; boat wins. Which choice best fits?
Need a hint?
  • Find the goal on the card. Compare cost, travel time, load size or the stated emissions total only for that goal.
  • Find the note for Greatest capacity. Check which words in this card match it.

Use the skills in a new task

Make four small boxes for Regional Economies and Networks, one for each lesson: Agriculture Manufacturing and Services; Transportation and Trade Costs; Imports Exports and Local Trade; A Trade-Off Needs a Goal. 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: Agriculture Manufacturing and Services; Transportation and Trade Costs; Imports Exports and Local Trade; A Trade-Off Needs a Goal.
  • 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

Agriculture Manufacturing and Services: The card says: “Fictional farm grows wheat.” That matches Agriculture. Agriculture is raising crops or animals for products. Compare: The card says: “Fictional factory turns cotton into cloth.” That matches Manufacturing. Manufacturing is making products by processing inputs. Transportation and Trade Costs: The card says: “Fictional cargo moves from ship to warehouse.” That matches Port. Port is a place where ships transfer people or cargo. Compare: The card says: “Fictional freight cars carry wheat over tracks.” That matches Railway. Railway is a transportation route using trains on tracks. Imports Exports and Local Trade: The card says: “Fictional Town A receives flour from Town B.” That matches Import. Import is a product entering the defined area from elsewhere. Compare: The card says: “Fictional Town A sends apples to Town B.” That matches Export. Export is a product leaving the defined area for sale elsewhere. A Trade-Off Needs a Goal: The card says: “Fictional costs: road $8, rail $6; rail wins this criterion.” That matches Lowest cost. Lowest cost is the smallest stated monetary total. Compare: The card says: “Fictional times: road two hours, rail four; road wins.” That matches Fastest arrival. Fastest arrival is the shortest stated travel time. 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.
