Why Are Some Nations Richer than Others?
Unit 4 · Lesson 4.1 · Last updated June 2026
A 45-minute card-sort lesson where students identify the six determinants of national wealth, dispel common misconceptions using real data, and connect prior learning to the drivers of prosperity — setting the stage for Unit 4.
Overview
Students are introduced to the way economists think about the wealth and poverty of nations. Through a hands-on card sort, they identify the six determinants economists agree are causally linked to national wealth, examine data that dispels common misconceptions, and connect what they've learned in previous units to Unit 4's big ideas. Note: The Student Handout references concepts from Units 1, 2, and 3. Consider adjusting the hints if students are not yet familiar with those concepts.
Learning Objective
- Identify factors that promote national wealth.
Materials
- Instruction Slides (display during class period)
- Determinant Cards p. 4 (Class Set — 1 copy per pair, cut into 12 cards; consider printing on cardstock and storing in envelopes or paperclipped)
OR - Digital Card Sort (make a copy for each student pair and enable editing access)
- Student Handout p. 5 (1 copy per student)
- Suggested Responses p. 6 (1 copy for educator reference)
Lesson Sequence
Slides 2–3
- Display Slide 2. Allow students a moment to consider the prompt, then call on several students to share their responses. Do not offer feedback at this point. (Additional educator tips and suggested answers are in the notes section throughout Instruction Slides.)
- Proceed to Slide 3. Identify the learning objective and explain that this lesson marks the start of Unit 4. Students will develop a more nuanced response to the activator throughout the unit — this lesson reveals an economist's answer to the prompt.
Slides 4–22
- Progress through Slides 4–5. Organize students into pairs and explain that economists consider six determinants on the Determinant Cards to be causally linked to national wealth, while the remaining cards represent commonly mistaken factors. Distribute 1 set of Determinant Cards (or a Digital Card Sort link) to each pair. Instruct pairs to sort the cards — remind them it's fine not to know all the answers and to focus on discussing and making their best guesses.
- Allow pairs 4 minutes to sort. Progress through Slides 6–7. Read the quote aloud and explain that while economists generally agree on which factors do and do not determine a nation's wealth, there is no universal agreement on which determining factors are most or least important — and a successful approach for one country cannot simply be replicated in another.
- Display Slide 8 to reveal the six factors economists agree are causally linked to national wealth. Instruct pairs to check their work and move any incorrectly categorized cards. Tell students not to write these down — they will receive a handout with the information shortly.
- Proceed to Slide 9. Allow approximately 1 minute for pairs to discuss the questions. Collect Determinant Cards and survey the class to gauge confidence and common surprises, questions, or curiosities.
- Advance through Slides 10–11. Click to reveal the text and acknowledge that it's understandable if students miscategorized some cards — there are examples of wealthy countries that also stand out in terms of some non-determinants (e.g., large population, powerful military, abundant natural resources), but the overall relationship between these characteristics and national wealth is weak.
- Display Slide 12. Tell students to consider the prompt as they examine data related to each of the non-determinants.
- Progress through Slides 13–19. Encourage students to review the data and identify counterexamples. Once pairs have briefly discussed, debrief as a class and explain how each counterexample demonstrates the weak relationship between that non-determinant and national wealth. (Additional explanation is in the notes section of Instruction Slides.)
- Proceed to Slide 20. Instruct students to discuss the question with a peer. Call on several students to share.
- Display Slide 21. Distribute 1 copy of Student Handout to each student and remind students that economists largely agree these six factors contribute to a nation's wealth.
- Proceed to Slide 22. Use the text on the slide to explain the task. Draw students' attention to the hints on the handout — this is an opportunity to connect learning from prior units to concepts they'll explore throughout Unit 4. Allow approximately 10 minutes for pairs to discuss and add their thoughts. Call on volunteers to share and elaborate as needed. (Reference Suggested Responses as needed.) Pro Tip: As students learn more about each factor throughout the unit, they can return to this handout and deepen their explanations.
Slides 23–24
- Progress through Slides 23–24. Instruct students to get out a half sheet of paper and follow the instructions on Slide 24.
- Collect half sheets and review responses for misconceptions or gaps in understanding. (Reference the slide notes as needed.)

What Educators Are Saying
I really enjoyed this lesson because it gave students a chance to look at data. The data in the slides was easy for most students to identify the outliers, and working in groups provided for great discussion.
The notes are incredibly helpful in preparing for the lesson.
Each lesson is carefully crafted and engaging and I appreciate the ideas!
