Unit review questions
1. Use the geographic notes. A card locates Gulf shoreline in southern Mississippi. Which choice best fits?
Need a hint?
  • Use the coast or water clue in the card: eastern ocean, western ocean, Gulf shoreline or freshwater Great Lakes.
  • Find the note for Gulf coast. Check which words in this card match it.
2. Use the geographic notes. A fictional facility refines a raw material. Which choice best fits?
Need a hint?
  • Look for a resource that can replenish, one that cannot on ordinary human timescales, a changed material or products moved toward users.
  • Find the note for Processing. Check which words in this card match it.
3. Use the geographic notes. Fictional area has 150 people across 3 square kilometres. Which choice best fits?
Need a hint?
  • Divide the number of people by the area. Keep the answer in people per square kilometre.
  • Find the note for 50 people per square kilometre. Check which words in this card match it.
4. Use the geographic notes. A table compares dollars with thousands of dollars without conversion. Which choice best fits?
Need a hint?
  • Check what differs between the two records: date, area boundary, measurement unit or what is counted.
  • Find the note for Unit mismatch. Check which words in this card match it.

Use the skills in a new task

Make four small boxes for United States Regions and Resources, one for each lesson: Atlantic Gulf Pacific and Great Lakes; Resources and Regional Production; Population Density Is a Ratio; Regional Data Need Comparable Definitions. 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: Atlantic Gulf Pacific and Great Lakes; Resources and Regional Production; Population Density Is a Ratio; Regional Data Need Comparable Definitions.
  • 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

Atlantic Gulf Pacific and Great Lakes: The card says: “A card locates ocean shoreline in the eastern United States.” That matches Atlantic coast. Atlantic coast is the eastern U.S. ocean coast. Compare: The card says: “A card locates ocean shoreline in California.” That matches Pacific coast. Pacific coast is the western continental U.S. ocean coast. Resources and Regional Production: The card says: “A fictional forest produces new tree growth over time.” That matches Renewable resource. Renewable resource is a resource that can replenish under suitable management and conditions. Compare: The card says: “A fictional region extracts coal deposits.” That matches Nonrenewable resource. Nonrenewable resource is a resource not replenished on ordinary human timescales. Population Density Is a Ratio: Divide people by area: 100 ÷ 10 = 10. The density is 10 people per square kilometre. This is an average across the stated area, not a count in every square. Compare: Divide people by area: 100 ÷ 5 = 20. The density is 20 people per square kilometre. This is an average across the stated area, not a count in every square. Regional Data Need Comparable Definitions: The card says: “Fictional comparison uses one region’s 1990 record and another’s 2020 record.” That matches Date mismatch. Date mismatch is records refer to different times. Compare: The card says: “Fictional comparison uses a city and its wider metropolitan area as if identical.” That matches Boundary mismatch. Boundary mismatch is records cover differently defined areas. 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.
