Trade-Offs and Opportunity Cost is a Grade 9–12 social studies worksheet that introduces foundational economics through decision-making. Students complete 10 questions—9 multiple-choice items and 1 multiple-select item—to identify that wants exceed available resources, define economics as the study of how people make decisions, and recognize that every choice has a cost. The worksheet distinguishes trade-offs, the alternatives available when a decision is made, from opportunity cost, the most important alternative given up. Students then apply these terms to Juan’s prioritized after-school choices. They identify all three alternatives he gives up by choosing work, select the football game as his opportunity cost, and connect that opportunity cost to the economic cost of his decision. This free printable worksheet with an answer key supports direct instruction, guided practice, review, or an introductory economics assessment. Its true/false, multiple-choice, and multiple-select formats help teachers check both vocabulary understanding and application of opportunity cost in a realistic scenario.

This Grade 9–12 worksheet uses 10 items—9 multiple-choice and 1 multiple-select—to build understanding of resource scarcity, economic decision-making, trade-offs, and opportunity cost. Students first identify key definitions and then apply them to Juan’s prioritized after-school choices by separating all forgone alternatives from the single most important alternative given up.
Introduce the worksheet by discussing how limited resources require people to choose among competing wants, then model the difference between a trade-off and an opportunity cost using a familiar decision. As students reach the Juan scenario, have them rank the alternatives aloud: choosing work creates several trade-offs, while the football game is the highest-priority alternative and therefore the opportunity cost. Use the true/false and vocabulary items before the scenario questions to check foundational understanding.
Students may define economics as simply studying money or getting rich instead of understanding it as the study of how people make decisions. In the Juan questions, a common error is selecting only the football game when asked for the trade-offs, or selecting every forgone option when asked for the opportunity cost. Students may also choose “going to work” as the cost even though it was the selected action, not the most important alternative given up.
Wayground provides this Trade-Offs and Opportunity Cost worksheet as a printable PDF and as a digital quiz, with a complete answer key for all 10 items. Printable submissions can be graded by scanning student work with the Wayground for Teachers app, while the digital quiz can be assigned and scored online. The printable format also gives schools an option for reducing screen time.
The worksheet uses Juan’s ranked decision to make the distinction concrete: the trade-offs of going to work are the football game, a friend’s house, and going home to sleep. Its later questions ask students to identify the football game as the opportunity cost because it is the most important alternative Juan gave up. This sequence moves students from recognizing all unchosen options to selecting the single highest-value one.
