A worksheet was never going to teach the psychology of peace.

Your students do not answer questions about the post-war conference. They sit inside a delegation and make the call. Each day opens with a Daily Release: a War Aftermath Briefing, a Humanitarian update, a domestic pressure card, a rival nation's proposal on the table. They read 3.6 million refugees, 85,000 stateless people, 85 percent industrial destruction in Athera, and then they decide what their nation will accept. Do they hold the Kessler Valley or trade it away. Do they punish Valdris or rebuild it. Every choice is made from evidence under pressure, with real stakes for the durability of the peace, not from a fill-in-the-blank prompt.

They are graded on their reasoning, not on whether the treaty holds.

The rubric makes the rule plain. A delegation that builds a punitive, failing treaty but writes a sharp metacognitive analysis of the biases that drove that failure scores higher than a delegation that stumbled into a durable peace by luck. The 100-point model puts 60 points on daily journal engagement, 20 on holistic quality with a focus on ethical reasoning, and 20 on the final reflection. Students are never penalized for a treaty that collapses. They are rewarded for catching the moment their own anchoring or naive realism pulled them off course. A sound process behind a broken treaty beats a lucky guess every time, and the rubric is written so your students can see exactly why.

Let the workbook hold the paperwork so students spend their energy on judgment.

The student workbook is a 10-sheet Excel hub built so the busywork disappears. Yellow input cells tell students exactly where their data goes. A Grievance Map keeps every nation's losses and demands in one place, so a delegate is weighing real positions instead of flipping through pages. A Bias Tracker asks students to name the cognitive pressure pushing on them each day and audit it against what they actually did. It runs through Google Classroom with no setup friction. The tracker does the bookkeeping of the negotiation so the thinking, the trade-offs between satisfaction and durability, stays where it belongs, in your students' hands.

Every day is already scripted. You bring the facilitation.

The teacher guide carries 12 daily scripted playbooks, the War Aftermath and Humanitarian briefings written for you, and cut-and-print domestic pressure cards that put political stakes on every delegation. You do not prepare the scenario, the numbers, or the hidden scoring. It is all written down, including the Starter Scripts for the Day 12 debrief, the questions that walk students back through the Just-World Hypothesis and the Distinction Bias they just lived. The simulation maps to class periods, not calendar days, and runs for any class from 12 to 35-plus students. You read the briefings with gravity, you ask the questions, and the design does the rest. Prep is light because the work is done.

The lesson plan is already written.

Every simulation comes with a fully editable, admin-ready lesson plan. Standards alignment, daily pacing, learning objectives, differentiation, and an assessment plan are already done, so you can hand it to an administrator or adapt it to your district template in minutes.

The moment the satisfying treaty turns out to be the one that fails.

Maya represents Corinth, a victor nation, and she wants Valdris to pay. The War Aftermath Briefing is still ringing in the room, the casualty figures, the resistance executions in Athera, and the math of justice feels simple. Her delegation pushes for crushing reparations and holds the Kessler Valley because Corinth currently holds it. The Satisfaction Score climbs. It feels like winning. Then Sevalon, the arms dealer who sold 2.4 billion in weapons to the aggressor, walks away rich and unpunished, and a rival delegation slides across a proposal that gives Corinth 85 percent of its demands. Maya stares at the 15 percent gap and prepares to reject it.

At the pivot she has to choose between the treaty that feels like justice and the treaty that might actually last. She kills the workable compromise over the 15 percent gap, the way her gut told her to. On Day 12 the Legacy Projection fast-forwards 5, 15, and 25 years. Valdris collapses economically, the punished population radicalizes, and the durable peace she could have signed never existed. Once she trusts the evidence instead of the moral intuition, she sees it. The boring compromise was the strong one all along, and knowing about bias did not protect her from it.

A post-war peace conference, and four nations who cannot all be right.

The war is over. Your students take seats inside the volatile delegations of a post-war peace conference, charged with drafting the treaty that decides what comes next. They represent Valdris, Corinth, Sevalon, or Athera, each carrying its own casualties, its own grievances, and its own domestic pressure. They negotiate over occupied territory, reparations, refugees, and the fate of 85,000 stateless people of mixed heritage. They are solving the Versailles Trap without knowing yet that is what it is called.

Engineering better thinkers.

Diplomacy is where discernment either holds or breaks. A treaty is built from competing evidence under emotional pressure, and the seductive choice is rarely the durable one. Each day pairs one cognitive bias with the capacity that defeats it, so students feel the pressure and practice the remedy in the same move.

13 days of evidence, negotiation, and consequence.

Day 0 arms students with the cognitive vocabulary they are about to ignore under pressure. From Day 1 the briefings, proposals, and domestic pressure cards build a negotiation that rewards the satisfying choice and quietly tracks the durable one. The arc bends toward Day 12, where the hidden score and the historical parallel finally land.

Standards alignment.

The Treaty maps to the C3 Framework for social studies inquiry and NCSS world history themes. Students evaluate sources and weigh competing evidence under D3.1.9-12 and D3.4.9-12, construct and defend arguments using specific claims and evidence under D4.1.9-12, and analyze multiple perspectives and the long-term consequences of decisions under D2.His.4.9-12 and D2.His.14.9-12. The negotiation work develops the communication and deliberation skills in D4.6.9-12 and D4.7.9-12. The historical-reasoning core, comparing the students' invented peace to the Treaty of Versailles in the final debrief, targets causation and continuity over time in line with NCSS Time, Continuity, and Change.
