Introduction
Critical Thinking About Geography: United States, Canada, and Greenland includes a collection of map activities that engage students in opportunities to practice and apply the geography skills and concepts that they’re learning. It contains 30 maps with 15 accompanying lessons. You may use these activities for whole-class, small-group, or individual instruction. A debriefing discussion after each map lesson provides an opportunity for students to reflect on their experiences and synthesize their thinking. It also provides an additional opportunity for informal assessment to assist instructional planning.
Implementation Guide The following guidelines will help you prepare for and use the activity sets in this text.
Preparing for Instruction
Each lesson consists of instructional notes that provide background information about each map, answers to the student activity sheet, suggestions for debrief/discussion, and suggestions for extending and enhancing learning. Each map is reproducible; you should also make additional resources available to students. Prepare copies of student activity sheets (one copy per student in the class). Distribute any additional materials (if described in the instructional notes). To keep students engaged, have them record their answers on their own sheets of paper.
Timing the Activities
The activities are designed to take approximately 20–30 minutes per lesson. If time is short, you might plan on having students complete half of the activities in one session, and the rest of the activities on a different day. For longer time frames, have students complete a group activity such as creating their own map. It is helpful to give students a “five-minute warning” before it is time to gather for a debrief discussion.
Debriefing the Activities
After students have completed the activities as a whole class, small groups, or individuals, bring them together for a brief discussion. At this time, you might have students pose any questions they had about the activities. Before responding to individuals, ask if other students encountered the same difficulty or if they have a response to the question. The class discussion is also a good time to draw out the essential ideas of the activities. The questions that are provided in the teacher’s notes for each activity set can serve as a guide to initiating this type of discussion. You may wish to collect the student activity sheets before beginning the class discussion. However, it can be beneficial to collect the sheets afterwards so that students can refer to them during the discussion. This also gives students a chance to revisit and refine their work based on the debriefing session.

lGoal: To provide opportunities for students to develop concepts and skills related to getting information from historical maps
National Geography Standards Standard 13. How the forces of cooperation and conflict among people influence the division and control of Earth’s surface.
Preparing Students for Instruction Before starting this activity, make sure that students know how to read a map legend.
Map Overview These three maps show the gradual growth of the United States in terms of how much land it held, from 1800 to 1860.
Answer Key 1. France and Spain
2. Indiana Territory, Territory Northwest of the Ohio River, Territory South of the Ohio River, and Mississippi Territory
3. Maine, Ohio, Indiana, Illinois, Alabama, Mississippi, and Louisiana (in any order)
4. Spain
5. Possible answers: It was a “claimed area;” it was bordered by Spanish and British territory.
6. Missouri was a “special status area.”
7. This map shows no foreign or special status territories.
8. California and Oregon
9. Answers will vary, but should recognize that the country grew westward during this period, and continually acquired territories and states until it reached from coast to coast by 1860. Land originally owned by France, Spain, and Mexico and claimed by Great Britain was obtained by the United States through treaty or purchase. Territories became states.

Discussion GuideTo support students in reflecting on the activities and to gather some formative information about student learning, use the following prompts to facilitate a class discussion to “debrief” the map activities.
Prompts/Questions
1. In which of these time periods do you think the United States grew the most and acquired the most new land?
2. Which territories became states between 1800 and 1820?
3. How did the United States acquire all the land from 1800 to 1860?
4. As the inhabited parts of the country grew and expanded, where did the country get the population to live there? Where did all these people come from?
Suggested Appropriate Responses
1. From 1800 to 1820. In 1800, the United States occupied only a small portion of the land area, about one-fourth. By 1820, its holdings had expanded all the way across to the opposite coast.
2. Part of Indiana Territory became the states of Illinois and Indiana; Territory Northwest of the Ohio River became Ohio; Territory South of Ohio River and Mississippi Territory became the states of Mississippi and Alabama.
3. By purchases and treaties with Spain, France, Mexico, and Great Britain
4. Most likely through immigration
Extending and Enhancing Learning
l Have students work in groups to research the process of a territory becoming a state. Assign each group a different territory. Each group does the research and then writes a report, which includes a map of the territory before it became a state or states, and a map of the new state or states.
l For students who need more support, have them work in groups to play a “Which State Am I?” game. First, each student in the group writes three questions on small pieces of paper that are hints about a state. For example, “I am a state that was first part of the territory of Indiana. In 1820, I was the state just west of a small part of Lake Michigan.” All questions are put in a container, a box, or a basket. To play the game, each player draws out a question and then uses the maps to decide on the answer. The author of the question determines if it was answered correctly. Correct answers earn one point. When all questions have been drawn and answered, the player with the most points wins the game.
l To challenge students further, have them research the period between 1800 and 1860 in U.S. history, then write the journal of someone who traveled west to places such as Oklahoma, California, or Oregon. Journals should include the reasons for the change of location, such as acquiring their own piece of land or (in California) hoping to get rich mining gold. Students can draw a picture of the character they are portraying, trying to include accurate information about dress of the time. Have students present their reports to the class. Students may wish to dress in costume while reading their “journals.”

Name:
Geography Vocabularyterritory: an area owned by a country such as the United States or Canada that is not a state or a province
lReading the Map of the United States in 1800Look at the first map. This map shows all of the United States in 1800. There wasn’t very much land, but the country had already grown. Kentucky, Vermont, and Tennessee had become states in the late 1700s. The striped and dark gray areas show that the United States claimed several territories, but the land west of the Mississippi River belonged to foreign countries.
lUnderstanding the Map of the United States in 1800 1. Which two foreign countries owned land near the United States?
2. What are the names of the territories owned by the United States in 1800?
lReading the Map of the United States in 1820Look at the second map. The United States had grown a great deal in 20 years. Part of this was due to the Louisiana Purchase in 1803, when the French government sold a large tract of land to the United States. Some of these changes and their dates are noted.
lUnderstanding the Map of the United States in 1820 3. Which new states had been added since 1800?
4. Which foreign country still owned land near the United States in 1820?
5. What do you notice about the area called the Oregon Country?
6. Why does Missouri look different from other areas on this map?
lReading the Map of the United States in 1860 7. Look closely at this map. Compare and contrast it with the two other maps. What do you observe?
8. What two states were on the west coast of the United States in 1860?
lAnalyzing the Maps 9. What were the major changes to the United States between 1800 and 1860? Explain.

Introduction
Critical Thinking About Geography: South America includes a collection of map activities that engage students in opportunities to practice and apply the geography skills and concepts that they’re learning. It contains 25 maps with 15 accompanying lessons. You may use these activities for whole-class, small-group, or individual instruction. A debriefing discussion after each map lesson provides an opportunity for students to reflect on their experiences and synthesize their thinking. It also provides an additional opportunity for informal assessment to assist instructional planning.
Implementation Guide The following guidelines will help you prepare for and use the activity sets in this text.
Preparing for Instruction
Each lesson consists of instructional notes that provide background information about each map, answers to the student activity sheet, suggestions for debrief/discussion, and suggestions for extending and enhancing learning. Reproduce each map and have additional resources available to students. Prepare copies of student activity sheets (one copy per student in the class). Distribute any additional materials (if described in the instructional notes). To keep students engaged, have them record their answers on their own sheets of paper.
Timing the Activities
The activities are designed to take approximately 20 to 30 minutes per lesson. If time is short, you might plan on having students complete half of the activities in one session, and the rest of the activities on a different day. For longer time frames, have students complete an additional group activity such as creating their own map. It is helpful to give students a “five-minute warning” before it is time to gather for a debrief discussion.
Debriefing the Activities
After students have completed the activities as a whole class, small groups, or individuals, bring them together for a brief discussion. At this time, you might have students pose any questions they had about the activities. Before responding to individuals, ask if other students encountered the same difficulty or if they have a response to the question. The class discussion is also a good time to draw out the essential ideas of the activities. The questions that are provided in the teacher’s notes for each activity set can serve as a guide to initiating this type of discussion. You may wish to collect the student activity sheets before beginning the class discussion. However, it can be beneficial to collect the sheets afterward so that students can refer to them during the discussion. This also gives students a chance to revisit and refine their work based on the debriefing session.

lGoal: To develop concepts and skills related to using maps to compare data affecting population density
National Geography Standards Standard 1. How to use maps and other geographic representations, tools, and technologies to acquire, process, and report information from a spatial perspective.
Standard 3. How to analyze the spatial organization of people, places, and environments on Earth’s surface.
Standard 12. The processes, patterns, and functions of human settlement.
Preparing Students for Instruction Before starting this activity, review the following with students:
l Explain the meaning of terms in the climate and population legends, such as “tundra” and “steppe,” that students may not know. Alternatively, have students look these up in a dictionary or online.
Map Overview The first three maps—precipitation, climate, and physical—show the factors that affect where people settle in a continent. The fourth map, population density, can be analyzed and compared with the other three to determine the impact these three factors have on population density.
Answer Key 1. 0 to 10 inches per year
2. A narrow strip of flat coastline with the Andes mountains behind it
3. Dry (steppe and desert)
4. More than 128 people per square mile; the dark areas surround the cities of Lima, Peru, and Santiago, Chile.
5. The coastal cities have relatively high population densities; however, the lack of rainfall, desert climate, and nearness to the mountains appear to have caused a relatively sparse population away from the cities.
6. The Andes mountains
7. Polar & alpine
8. Answers may vary, but students should predict a low population. Mountains are difficult to inhabit, and the dry climate prevents agriculture. Transportation is also difficult.
9. Answers will vary.

Discussion GuideTo support students in reflecting on the activities and to gather some formative information about student learning, use the following prompts to facilitate a class discussion to “debrief” the map activities.
Prompts/Questions
1. Think of the two regions you have examined on these maps. What reasons can you give for their population densities?
2. What explanation can you give for the larger population density on the northern part of the coastal strip?
3. If you lived in the Andes mountains area of South America, what are some ways you might earn a living?
Suggested Appropriate Responses
1. The narrow strip of land doesn’t have much fresh water, necessary for survival. On the other hand, its coastal location could provide fish for food, and shipping and other transportation industries. The Andes mountains are steep and difficult to inhabit because of both climate and landform.
2. Answers may vary. Students may speculate that since the northern part is closest to the equator, its climate may be warmer and more habitable than the southern area. The area near 10 degrees south receives more rainfall.
3. Answers will vary but may include lumbering and some agriculture.
Extending and Enhancing Learning
l Have students investigate other areas on the map of South America, such as the Amazon basin, and report on the effects of landforms, climate, and precipitation on population density in those areas.
l For students who need more support, have them make a chart of information about the two areas discussed in this lesson. Headings should be: Climate, Precipitation, Landforms, Population. After filling in the chart, students will have visual evidence of the relationships. Have them put in the same information about one other South American area.
l To challenge students further, have them research the original settlement by Spanish or Portuguese explorers of one of these areas. What geographic reasons prompted where these people settled? Were the reasons different from those examined in this lesson: climate, precipitation, and landforms? Were there personal reasons such as greed for gold or religious reasons? Were the settlers escaping something unpleasant? How did the native South Americans handle the arrival of Spanish settlers? How did these two groups treat each other?

Geography Vocabularyalpine climate: a cold climate above the tree line
polar climate: a climate too cold to support the growth of trees
population density: the number of persons per given unit of space
precipitation: rain, snow, sleet, or hail
lReading the MapsPopulation density means how many people live in a certain amount of space. Look at the maps that give information about the climate, precipitation, and landforms of a particular area. As you look at these maps, compare each one with the population density map. Which factors—climate, precipitation, or landforms—seem to have affected settlement in a particular area? All of these factors have some effect.
lUnderstanding the Maps 1. Look first at South America’s west coast. On the precipitation map, locate the narrow strip of
coastal land that ranges from 5 degrees below the equator to 30 degrees below. What is the annual precipitation for that area?
2. On the physical map, what landform(s) do you find in the same area, 5 degrees to 30 degrees below the equator?
3. On the climate map, what is the average climate for this same area?
4. Look at this same area on the population density map. There are two dark areas, one in the northern part of the coastal strip, and one in the southern part. What is the population density for these two areas? What geographic feature might explain this? (Hint: Compare the population map to other maps.)
lAnalyzing the Maps 5. How do the climate, precipitation, and landforms seem to have affected the population density in
this area?

lUnderstanding the Maps 6. Examine the physical map. Look at the area directly east of the coastal strip. What landform
is there?
7. What is the climate throughout most of this landform, beginning at 10 degrees below the equator?
lAnalyzing the Maps 8. Without looking at the population map, predict the population density of the area described in
questions 6 and 7.
9. Check your prediction. Were you right?
