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

Objectives

Students will be able to:

  • Define assets, liabilities, and equity
  • Use the equation Assets = Liabilities + Equity
  • Show how a single transaction affects both sides of the equation

Materials

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

Key vocabulary

Assets
Things the business owns that have value: cash, inventory, equipment, buildings, and money customers owe it (accounts receivable).
Liabilities
What the business owes others: loans, unpaid bills to suppliers (accounts payable), and wages owed.
Equity
What's left for the owners after subtracting liabilities from assets. It includes money owners put in plus profits kept in the business.

45-minute agenda

  1. 0–5 min

    Warm-up

    Post: “List three things you own and one thing you might owe someday. What would be left if you sold everything and paid every debt?”

    Teacher note: That leftover amount is equity — net worth.

  2. 5–17 min

    Direct instruction

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

    • Assets = what you own. Liabilities = what you owe.
    • Equity = assets − liabilities.
    • Assets = Liabilities + Equity, always.
    • Equity is a business's net worth.

    Use the “See it” slide (A lemonade stand's assets, liabilities, and equity) to make the idea visual.

  3. 17–22 min

    Worked example

    Walk through “One purchase, both sides” on the slides. Pause before the result and ask students to predict it.

  4. 22–32 min

    Keep It Balanced

    Format: pairs · 10 minutes

    1. A lemonade stand starts. Step 1: the owner puts in $100 of her own cash. Step 2: she borrows $50 from a parent. Step 3: she spends $40 of cash on supplies.
    2. After each step, pairs record cash, supplies, liabilities, and equity in a T-chart.
    3. Pairs check that Assets = Liabilities + Equity after every step.

    What to look for: Step 1: assets $100 cash = $0 liabilities + $100 equity. Step 2: $150 cash = $50 + $100. Step 3: $110 cash + $40 supplies = $150 = $50 + $100. Buying supplies only changes the mix of assets.

  5. 32–37 min

    Check for understanding

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

    1. What is its equity? — D. $300,000
    2. Which of these is a liability? — B. An unpaid bill owed to a supplier
    3. If a company buys equipment with a loan, its equity immediately goes up. — False
  6. 37–42 min

    Discussion

    • What are your own assets and liabilities? What's your net worth?
    • Why might a company choose to borrow money instead of using owners' money?
  7. 42–45 min

    Exit ticket

    Prompt: Write the accounting equation and explain it in your own words.

    Answer: Assets = Liabilities + Equity: everything a business owns was paid for either by borrowing or by the owners.

Differentiation

Common misconception

“Taking out a loan makes a business richer.” It adds cash and an equal debt — equity doesn't change.

Support

Provide a T-chart with “Owns” and “Owes + Owners' share” headings.

Extension

Add Step 4: the stand sells all its supplies as lemonade for $90 cash. What happens to each part of the equation? (Cash $200, supplies $0, liabilities $50, equity $150.)
