Negotiate a Shared River Decision
Use a bounded resource scenario to support a proposal and respond to a competing claim.
Mr. S Teaches · Original starter mini-lesson · MS7-SOC-06Learning objective
Write a negotiation proposal citing two data points, an opposing concern and a measurable compromise.
Before you begin
- Understand upstream/downstream and compare whole-number quantities.
Gather your materials
- Paper or notebook
- Pencil and the passage, model directions or data printed in this lesson
Language to know
- stakeholder
- A person or group affected by a decision.
- allocation
- How a limited resource is divided among uses.
- compromise
- An agreement in which parties adjust some preferences.
Understand the concept
Original fictional negotiation brief: Upstream Town U and downstream Town D share a river with 100 water units available in the dry-season planning model. U requests 60 for farms; D requests 50 for homes and workshops. A habitat assessment in the model recommends leaving 20 units in the river. The towns’ total requests plus habitat allowance exceed the available amount. U’s delegate argues that farms provide food and income; D’s delegate argues that downstream users should not bear all reductions. The model omits legal rights, timing, water quality and uncertainty in actual flows.
Teach it step by step
- Read the brief and list each stakeholder’s stated concern without ranking people’s worth.
- Calculate the total demand including the habitat allowance and the amount exceeding supply.
- Draft an allocation that respects 100 units and compare the reductions faced by U and D.
- Write a proposal with evidence, a response to a competing concern and a plan for revisiting the agreement if river conditions change.
Make the thinking visible
Worked example or model response
Requests total 60 + 50 + 20 = 130, which is 30 above available water. One possible allocation is U 45, D 35 and habitat 20. It balances the arithmetic and gives each town a 15-unit reduction, but equal reductions are not automatically equitable or legally appropriate.
Guided practice
Together compare equal absolute cuts with equal percentage cuts. Explain why a fair-sounding rule still requires discussion of consequences and missing evidence.
Independent practice
Write a 120-word proposal with a numerical allocation, two supporting details, an acknowledged concern and a monitoring or renegotiation trigger. Label it as a classroom model rather than advice for an actual water dispute.
Quick assessment
Would leaving the habitat allowance out solve the allocation problem without creating a new tradeoff?
Answer key & assessment criteria
Answers and teaching guidance
- Guided: Equal 15-unit cuts take different percentages from U’s 60 and D’s 50; proportional cuts would distribute reductions differently. Fairness depends on justified priorities and constraints.
- Independent: Accept allocations totaling no more than 100, with the habitat decision explicit, accurate use of at least two numbers and a reasoned response to another stakeholder.
- Quick check: No. It changes an ecological priority and may create other costs; arithmetic feasibility does not remove tradeoffs.
Look for: Look for a claim that answers this lesson’s question, accurate use of the supplied evidence and an explanation of a limit or alternative. Ask the learner to point to the detail supporting each inference.
Make it work for your learner
More support
Use 100 paper tokens divided among three labeled areas and offer a claim–evidence–concern writing frame.
Extension challenge
Introduce a dry-year estimate of 80–110 units and develop a conditional allocation rule rather than one fixed number.
