Topic-level alignment by FLC. How we map standards
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
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.
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.
17–22 min
Worked example
Walk through “One purchase, both sides” on the slides. Pause before the result and ask students to predict it.
22–32 min
Keep It Balanced
Format: pairs · 10 minutes
- 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.
- After each step, pairs record cash, supplies, liabilities, and equity in a T-chart.
- 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.
32–37 min
Check for understanding
Use the question slides — or run them as a Four Corners game. Questions:
- What is its equity?
- Which of these is a liability?
- If a company buys equipment with a loan, its equity immediately goes up.
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?
42–45 min
Exit ticket
Prompt: Write the accounting equation and explain it in your own words.
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.)
