Learning objective
Calculate a constant opportunity cost and explain its dependence on the model’s assumptions.
Before you begin
- Calculate totals and compare alternatives under a fixed constraint.
Gather your materials
- Paper or a note-taking document
- Pencil; the original lesson texts and records below
Language to know
- Scarcity
- A condition in which available resources cannot satisfy every desired use.
- Opportunity cost
- The next-best alternative forgone when a choice is made.
- Marginal choice
- A decision about one additional unit or change.
Understand the concept
Classroom model: a workshop has 12 machine-hours. One stand requires 2 hours and one tray 1 hour; no setup time or other constraint is included. If all time goes to stands,6 can be made; if all goes to trays,12 can be made. Producing one more stand uses time that could make 2 trays. The opportunity cost is the next-best use given up, not every imagined alternative added together. These invented quantities illustrate a tradeoff rather than describe a real business or prescribe a financial decision.
Teach it step by step
- Make a table for 0,2,4 and 6 stands and the maximum trays remaining.
- Explain why combinations using more than 12 hours are infeasible under the model.
- Calculate the change in trays when one additional stand is chosen.
- Write an explanatory note linking the table to a stated production choice and one omitted real-world constraint.
Make the thinking visible
Worked example or model response
“Four stands use 8 hours, leaving 4 for trays. Moving from 4 to 5 stands reduces trays from 4 to 2, so the added stand costs 2 trays in forgone output. The constant tradeoff follows the fixed time requirements; setup or bottlenecks could change it.”
Guided practice
Together evaluate the proposed combination 5 stands and 4 trays. Calculate its resource use before judging feasibility.
Independent practice
Complete the four-row table and write 120 words explaining the opportunity cost of moving from 2 to 4 stands. Identify the next-best alternative under the stated assumption that trays are the only other use.
Quick assessment
Why does a zero-dollar price not necessarily mean zero opportunity cost?
Answer key & assessment criteria
Answers and teaching guidance
- Guided:5×2+4×1=14 hours, exceeding 12, so the combination is not feasible in the model.
- Independent:0 stands→12 trays;2→8;4→4;6→0. Moving 2 to 4 stands forgoes 4 trays. Explanation must state the fixed time assumptions and not generalize the ratio to every workshop.
- Quick check: Time or another scarce resource can have a forgone alternative even when no money changes hands.
Look for: Independent:0 stands→12 trays;2→8;4→4;6→0. Moving 2 to 4 stands forgoes 4 trays. Explanation must state the fixed time assumptions and not generalize the ratio to every workshop. Accept a different conclusion when it addresses the task and is supported by the supplied material.
Make it work for your learner
More support
Use 12 paper hour tokens and exchange 2 for each stand; keep units visible.
Extension challenge
Add a one-time setup of 2 hours for any stand production and explain where the tradeoff is no longer described by the original table.
