Students use proportional relationships, unit rates, rational number operations, and integer exponents to design a fair, welcoming community space that fits real limits of area, materials, and cost. Working with the Site Facilities Department, they compare layout options, graph relationships, build scale drawings, and revise their plans through critique, sticky-note feedback, and a before-and-after analysis. The work leads to a public presentation and design portfolio that show how mathematical evidence shaped stronger decisions for different community users.

Students will apply integer exponents, unit rates, proportional relationships, and rational number operations to create accurate scale drawings, compare layout options, graph proportional relationships, and justify choices about space, materials, and cost. Students will work with peers and the Site Facilities Department to design, critique, and revise a community space plan that is fair, welcoming, and responsive to real constraints and user needs. Students will give and use specific feedback during a sticky-note gallery walk and partner critique, then create a before-and-after comparison that explains how mathematical evidence improved their design. Students will present a final model, expo board, and short audio or video reflection that communicates their reasoning, teamwork, and learning clearly to visitors.

Throughout the project, teams create draft site maps, scale drawings, unit-rate and cost comparison charts, proportional graphs, and sticky-note critique records that document how their ideas change over time. They also produce a tagged revision set after feedback from the Site Facilities Department, identifying one layout choice to keep, one to change, and one to test again with measurement and cost evidence. By the end, students present a revised scaled park model and an expo board or digital display that includes the final layout, graphs, calculations, and a clear before-and-after comparison. Each team also submits a design portfolio with the approved plan, critique evidence, revision notes, and a short audio or video reflection explaining how the math and teamwork strengthened the final proposal.

Begin with a “Design Under Pressure” challenge in which teams use a simple site map from the Site Facilities Department, a fixed budget, and a few user cards to sketch a quick park layout that must fit scale and cost limits. Have teams post their first-draft ideas, then do a fast gallery walk where peers leave one warm and one cool sticky-note connected to space use, fairness for different users, and math evidence such as unit rates or proportional fit. Follow with a short partner interview or video message from the Site Facilities Department about real community needs and constraints, then ask students to notice what information they still need to answer which layout works best. Close by introducing the final model, expo board, before-and-after comparison, and reflection so students see that revision, feedback, graphs, scale drawings, and calculations will drive the work.

Host a community design expo where teams present their revised park model, scale drawing, graphs, unit-rate and cost evidence, and expo board to families, peers, and the Site Facilities Department. Set up each display to include the final approved layout, sticky-note critique evidence, and a clear before-and-after comparison showing how feedback changed the design to better meet space, materials, cost, and user needs. Invite visitors to ask questions and leave response cards on which layout choices seem most fair, useful, and welcoming for different users. Include a station for students’ short audio or video reflections so guests can hear how teamwork and mathematical decisions strengthened the final proposal.
