  • 45 minutes
  • Grades 9–12
  • Intermediate
  • Activity: small groups
Present slidesWorksheet + keyStudent lesson

Objectives

Students will be able to:

  • Explain what owning a share of stock means
  • Describe the two ways stock investors can earn a return
  • Calculate a company's market capitalization

Materials

  • Slide deck and a projector
  • Worksheet (one per student)
  • Exit ticket slips (bottom of the worksheet)

Key vocabulary

Market capitalization
A company's total stock market value: share price × number of shares. It's how people compare the size of public companies.

45-minute agenda

  1. 0–5 min

    Warm-up

    Post: “If you owned one share of a company you use every day, what would you actually own?”

    Teacher note: A tiny slice of the whole company — its profits, assets, and future — not a product or a store.

  2. 5–17 min

    Direct instruction

    Present the lesson slides. Make sure students leave with these points:

    • Stock = ownership in a company.
    • Returns come from price changes and (sometimes) dividends.
    • Prices move on expectations, not just results.
    • Market cap = share price × shares outstanding.
    • One company is a concentrated risk.

    Use the “See it” slide (How a stock works) to make the idea visual.

  3. 17–22 min

    Worked example

    Walk through “Why a stock dropped on good news” on the slides. Pause before the result and ask students to predict it.

  4. 22–32 min

    Headline Reactions

    Format: small groups · 10 minutes

    1. Read five made-up headlines: (1) “Company's profit rises 10%, but it expected 25%”; (2) “Company loses money, but losses were half what analysts expected”; (3) “New CEO announces bold expansion”; (4) “Company's biggest product recalled”; (5) “Company raises its dividend.”
    2. Groups predict whether each stock would likely rise or fall, and explain why using the word “expectations.”
    3. Compare predictions with the lesson's example of a stock dropping on good news.

    What to look for: (1) likely falls — good, but worse than expected. (2) could rise — bad, but better than expected. (3) uncertain. (4) likely falls. (5) often rises. Prices move on results compared with expectations.

  5. 32–37 min

    Check for understanding

    Use the question slides — or run them as a Four Corners game. Answers:

    1. What do you own when you buy a share of stock? — B. A small piece of ownership in the company
    2. What's the most likely explanation? — A. Investors expected even better results, so the price adjusts to the disappointment.
    3. All companies pay dividends to their shareholders. — False
  6. 37–42 min

    Discussion

    • Why might someone want to own a small part of a company they use every day?
    • Should stock prices be driven by investor mood? What problems does that create?
  7. 42–45 min

    Exit ticket

    Prompt: Why can a stock fall even when the company reports good news?

    Answer: Prices reflect expectations. If results are good but not as good as investors expected, the price can drop.

Differentiation

Common misconception

“A $5 stock is cheaper than a $500 stock.” Share price alone says nothing — compare market cap and earnings.

Support

Give the market cap formula with a worked example using small numbers (10 shares × $3).

Extension

Pick a public company and find its market cap and its dividend (if any). Explain what each number means.
