What This Standard Means
What Students Need to Do
- Students choose between real options when money, time, and workers are limited. They identify what they give up, what shapes their choice, which resources they need, and why both sides might agree to a trade.
What Mastery Looks Like
- Given two possible fundraisers and a club budget, a student picks one and explains why. They name the best option they gave up, the resources they need, and how a buyer and seller could both benefit.
Common Misconceptions
- Students may call every rejected option an opportunity cost, rather than the best one they gave up. They may count only money as scarce and overlook time or workers. Some think both sides must receive the same thing for a trade to make sense.
How to Assess It
- A club has $200, two volunteers, and one afternoon for either a car wash or a bake sale. Choose one, then name a scarce resource, the best option given up, one incentive, needed resources, and a trade both sides would accept.

Ways to Teach It
Give groups $30 in play money and school fair supply cards; have them plan one booth and name the best option they dropped.
Ask students to write: 'Should our school buy water refill stations or sports equipment with $500?' Require a reason and the forgone option.
Run a trading round with cards for tables, workers, ingredients, and cash; groups must make agreed trades to open a snack stand.
Compare two grocery flyers; students plan a $25 dinner, name what they cannot buy, and explain how sale prices affect their choices.
