Assess Grade 3–5 students' ability to create a model town plan that balances housing, jobs, schools, parks, and transportation under limited resources; students must produce a simple scaled layout or labeled map, allocate budget and land for each need, explain trade-offs and prioritization, and submit a short persuasive proposal defending their choices to community stakeholders. Testable skills: spatial reasoning, resource allocation, civic decision-making, and persuasive writing. Provide constraints such as population size, total budget, land area, and at least three competing demands to resolve.
