Examine how producers and consumers respond to scarcity by making choices involving opportunity costs and tradeoffs.

Oklahoma Academic Standards for Social Studies (2026) · E.C.1

Teacher's field guide

What Students Need to Do: Students decide how to use limited money, time, or supplies as buyers and producers. They explain what each choice gains and gives up. They identify the best alternative not chosen.
What Mastery Looks Like: Given one oven hour, a student can explain why a bakery makes bread instead of muffins and name the muffins as its opportunity cost. With a fixed lunch budget, the student can explain what buying one meal means giving up.
Common Misconceptions: Students may call every rejected option the opportunity cost, rather than the best one they passed up. They may think only shoppers face scarcity, or that a choice has no cost when no money changes hands.
How to Assess It: Exit ticket: A bakery uses its last bag of flour for bread instead of muffins, and you spend your last $8 on lunch instead of a movie ticket. For each choice, name what is gained and the best alternative given up.

Lesson moves

Ask: A bakery has one oven hour left. Should it bake bread or muffins? Write what the bakery gains and gives up.
Run three rounds of a $15 lunch-budget game with changing prices; students record each purchase and its next best alternative.
Use a grocery ad to plan a $25 dinner; students explain which food they left out and why.
