What This Standard Means

What Students Need to Do

Students explain why someone might borrow money when they cannot pay for something right away. They identify the borrower, lender, amount owed, and interest, then explain who must repay the money.

What Mastery Looks Like

Given a short scenario, students can identify why credit was used and name the borrower and lender. They explain that the borrower repays the borrowed amount, often with an added interest charge.

Common Misconceptions

Students may think credit is free money or the same as income. They may confuse credit with debit, or think interest is charged only when a payment is late.

How to Assess It

Give this exit ticket: “Maya borrows $60 from a bank and repays $66. Name the borrower, the lender, and what the extra $6 represents.”

  2. Discuss when borrowing might help someone, then have students write three sentences explaining the borrower’s responsibility.

  3. Sort scenario cards into credit or not credit, then earn points by identifying the borrower, lender, and interest.

  4. Compare a store’s cash price and payment plan, then circle the total repaid and discuss why the totals differ.
