Students will launch the community space design challenge by examining real site maps, photos, and measurement data, listening to a local planning perspective, and producing an initial evidence-based empathy artifact that captures user needs, mathematical constraints, and a first claim about what would make the space more fair and welcoming.

Students will synthesize user needs, site measurements, and proportional reasoning evidence into a clear How Might We problem statement and an initial team design brief that can guide later sketching, testing, and revision.

Students will generate multiple math-backed design ideas for a welcoming community space, compare those ideas using unit rates and proportional reasoning, and select one promising direction to carry into drafting.

Students will create a first-draft scaled community space plan or model that uses unit rates, proportions, and rational number calculations to justify layout, materials, and access choices before peer testing in the next phase.

Students will test their draft community space plans with peers and a local design professional, gather targeted feedback on unit rates, proportions, fairness, and usability, and document specific revisions they will make before the next draft.

Students will use a structured gallery walk and revision conference to critique draft community space plans, give evidence-based feedback on unit rates and proportions, revise their design choices, and document how mathematical reasoning improved fairness, usability, and welcome for different users.

Students will present a before-and-after comparison of their revised welcome space plan, cite mathematical evidence and peer/community feedback that shaped the revision, and document what they learned about designing fair, useful shared spaces.
