Two Numbers, One Question

Teacher writes on the board: China: 24,454 participants, 53,568,436 points. USA: 2,331 participants, 674,966 points.

China has about 10× the participants of the USA. Roughly how many times more points does China have?
Is China’s advantage only about having more people? How could you check?
If you ran the USA team, would you rather have 10× more participants, or participants who each score 10× higher? Why?

P — PRESENTATION · 20 minutes

Introducing Score-per-Participant + Comprehension Check

Teacher introduces the formula: score ÷ participants = score per participant. Model it together with China: 53,568,436 ÷ 24,454 ≈ 2,191 points per participant. Then the USA: 674,966 ÷ 2,331 ≈ 290 points per participant.

Word	Meaning
ratio	a relationship between two numbers showing how many times one contains the other
efficiency	how much output is produced per unit of input — here, points per participant
scale	the size of an operation — here, the number of participants
outlier	a data point far above or below the rest of the pattern
hedge (v.)	to soften a claim so it isn’t stated as 100% certain (this may suggest…)

Comprehension check (pairs, 5 min): Is China’s per-participant score (2,191) higher or lower than the USA’s (290)? By roughly how many times? (Answer: about 7–8 times higher — so the gap is not only about scale.)

P — PRACTICE · 25 minutes

Guided Practice — Complete the Ratio Table

In pairs, with a calculator, complete the Score per Participant column. Two rows are done for you.

Rank	Country	Participants	Score	Score / Participant
1	Mainland China	24,454	53,568,436	2,191
2	India	52,650	14,474,518	?
3	Kenya	28,417	14,410,481	?
4	Vietnam	8,229	4,628,973	?
5	Taiwan	1,747	1,737,107	?
6	South Korea	3,099	1,666,464	?
7	Nigeria	11,701	975,163	?
8	Singapore	1,088	770,343	?
9	United States	2,331	674,966	290
10	Thailand	1,222	642,805	?

Now re-rank: On a separate line, order all 10 countries by score-per-participant instead of total score. Where does the USA land? Where does Nigeria land? What surprises you?

Answer key (score per participant, rounded): India 275 · Kenya 507 · Vietnam 563 · Taiwan 994 · South Korea 538 · Nigeria 83 · Singapore 708 · Thailand 526. Re-ranked by efficiency: China (2,191) · Taiwan (994) · Singapore (708) · Vietnam (563) · South Korea (538) · Kenya (507) · Thailand (526) · USA (290) · India (275) · Nigeria (83). The USA moves from 9th (by total score) to 8th (by efficiency) — barely better, and still near the bottom of this Top 10 by either measure.

P — PRODUCTION · 25 minutes

Students Produce: Discussion → Written Argument

Card A — China's Outlier Number

China’s 2,191 points per participant is far above everyone else. What could explain a number this high — individual skill, team submissions counted per member, more experienced researchers, something else? You don’t have to be sure. Practice hedging: “This may suggest…”, “One possible explanation is…”

Card B — Two Strategies

Nigeria has 11,701 participants but only 83 points each. Taiwan has 1,747 participants but 994 points each. Both are “behind” China. Which country is in a better position to climb the leaderboard by 2027, and why?

Written Production (choose one, 150–200 words):

Strategy Memo: Advise the USA team. Should it recruit more participants (scale), train existing participants to submit better alphas (efficiency), or both? Use at least two numbers from the table and at least one hedge.
Country Case Study: Pick any country except the USA and China. Explain its position using both total score and score-per-participant. What does each number tell you that the other doesn’t?

Self-Study Quiz + Forward Link

Works in class or alone. Answers below — cover them and check yourself after.

Wrap-Up Quiz — 5 Questions

1. What is score-per-participant a measure of?

(a) total scale
(b) efficiency
(c) rank

2. True or False: The USA's main problem in 2026 is only that it has too few participants.

3. Which country has the highest score-per-participant in the Top 10?

4. Fill in the hedge: “____________ China's institutions submit team alphas that count for each member.” (this may suggest / it is possible that)

5. Nigeria has more participants than Vietnam but a lower score-per-participant. Which country is winning on scale, and which is winning on efficiency?

Answers: 1—(b) efficiency · 2—False, its per-participant score also lags most of the Top 10 · 3—China (2,191) · 4—either hedge works grammatically · 5—Nigeria wins on scale, Vietnam wins on efficiency.

Open platform.worldquantbrain.com → Competitions → IQC 2026. Recalculate the USA's current score-per-participant with today's live numbers. Has it changed since May?

Forward link — Lesson 07: Efficiency isn’t abstract — it’s built one alpha at a time. In Lesson 07, you submit one, and the USA's per-participant number moves because of you.

Teacher Notes — This lesson only works if students actually do the division in Practice — don't hand them the answer key early. Calculators or phones are fine; the skill being taught is reading a ratio and reasoning about what it hides, not mental math.

China's outlier number: The lesson deliberately does not resolve why China's per-participant score is so high. Real leaderboards contain numbers whose causes aren't fully known from the data alone — that's a genuine research/data-literacy lesson, not a gap in the material.

Self-study use: This lesson was designed to also work without a teacher present. A student can complete Warm-Up through Production alone using a calculator and the answer key in Practice, then self-grade with the Wrap-Up quiz.
