What This Standard Means

What Students Need to Do

Students choose whether to spend money now or save it for later. They identify the next best choice they give up and explain why it is the opportunity cost.

What Mastery Looks Like

Given a spending or saving choice, a student names the selected option and the next best option not chosen. The student explains the tradeoff using a complete sentence.

Common Misconceptions

Students may think opportunity cost means the price of an item or the money left over. They may list every missed option instead of the next best option.

How to Assess It

Exit ticket: Maya has $8 and can buy a game today or save for a $15 book. If she buys the game, what is her opportunity cost?

Ways to Teach It

  1. Give pairs 10 play dollars and choice cards for a toy, snack, or savings goal, then have them name what each choice gives up.

  2. Ask, “Would you spend $5 now or save it for a class trip?” Students defend their choice and name the missed option.

  3. Play Choice Match: students pair each spending or saving decision card with the card showing its opportunity cost.

  4. Use a grocery ad and a $12 budget; students select one item and explain what they cannot buy or save.
