Essential Question
Submission Required
Students rotate through a whole-class launch with station sets that include neighborhood park or plaza photos, a simple site map, measurement cards, material cost data, and short user scenarios. A local parks planner, city engineer, or architect introduces one real design challenge and highlights how site measurements, access, safety, and cost shape decisions. In teams, students annotate a shared empathy-and-evidence capture sheet with at least two user needs, two site constraints, and quick math observations such as space per person, distance comparisons, or material unit rates, then post a brief team claim about what the space must prioritize.

|---|---|
| 1 | Launch the challenge by posting the essential question, introducing the community partner, and setting the purpose for the walk. The partner shares one real design challenge, names a few user groups, and highlights how measurements, safety, access, and cost affect community decisions. Students form teams, take roles, and receive the empathy-and-evidence capture sheet. (10 min) |
| 2 | Model one sample station as a whole class. Demonstrate how to read a photo, site map, measurement card, and user scenario; then think aloud to identify one user need, one site constraint, and one quick math observation such as a unit rate, scaled comparison, fraction distance, or cost ratio. Clarify expectations for evidence-based notes and respectful team talk. (8 min) |
| 3 | Rotate through the first half of the Needs and Numbers Walk stations in teams. At each station, students observe visuals, read the scenario, calculate quick ratios or unit rates, compare proportional layouts, and record evidence about who the space serves, what limits the design, and what math matters. The facilitator and partner circulate to question student reasoning and push for precise calculations. (16 min) |
| 4 | Pause for a midpoint gallery walk and critique. Teams leave their capture sheet open, rotate once, and use sticky notes to give one suggestion focused on unit rates or proportions to another team. Each team reads the feedback they receive and adds a short revision note to update or sharpen one of their math observations or priorities before continuing. (8 min) |
| 5 | Rotate through the remaining stations and refine the team claim. Students continue gathering evidence, solve one additional multistep ratio, percent, or rational number problem from the station data, and then agree on a brief claim about what the community space must prioritize to be fair, useful, and welcoming. (10 min) |
| 6 | Share claims and close with reflection. Teams post and briefly present their claim using at least one piece of empathy evidence and one math justification. Then students complete the exit task by adding one class-chart claim about how math improved their early plan and one goal for contributing more thoughtfully in future teamwork. (8 min) |
Preparation (10 items)
- Create 4-6 station sets with neighborhood park or plaza photos, a simple site map, measurement cards, material cost data, and short user scenario prompts that include opportunities for unit rates, proportions, ratios, percents, and rational number operations.
- Invite and confirm a local parks planner, city engineer, architect, or contractor; provide the activity purpose in advance and ask them to bring one authentic design challenge plus any real map, measurement, safety, or materials data they can share.
- Prepare one empathy-and-evidence capture sheet per team with labeled spaces for at least two user needs, two site constraints, math observations, feedback revisions, and a final team claim.
- Write and post the essential question and create a visible role chart for teams such as reader, recorder, calculator, and discussion lead so collaboration is structured from the start.
- Develop a teacher model for one sample station that shows how to move from observation to evidence to a quick calculation and then to a design inference.
- Set out sticky notes for the midpoint critique and create a prompt card that asks students to leave one suggestion specifically about unit rates or proportions.
- Prepare chart paper or a display wall for teams to post final claims and for students to add their end-of-class reflection claim and contribution goal.
- Check that calculators, rulers, clipboards or hard writing surfaces, pencils, and any enlarged maps are ready so students can move efficiently between stations.
- Review station numbers and timing cues in advance so transitions are fast enough to keep the full rotation, critique, and reflection within 60 minutes.
- Plan supports for mixed readiness, including optional sentence frames, pre-highlighted data on selected cards, and extension prompts that ask students to compare multiple layout options or justify why one proportional design is fairer.
Student-facing instructions
You will work with a team to investigate how math and empathy can guide the design of a shared community space. At each station, you will examine photos, a site map, measurement or cost data, and a short user scenario. Your task is to identify who needs the space, what constraints affect the design, and what math helps you compare options fairly. Use your team capture sheet to record at least two user needs, at least two site constraints, and several math observations such as space per person, distance comparisons, cost per square foot, percent of space used, or fraction-based measurements. You will take team roles so everyone contributes: one person reads, one records, one calculates, and one helps the team discuss and decide. Midway through the activity, you will participate in a gallery walk and leave one sticky-note suggestion for another team about unit rates or proportions. After reading the feedback your team receives, you will revise at least one part of your thinking. At the end, your team will post a short claim explaining what the community space must prioritize and support it with empathy evidence and math evidence. Then you will complete an exit reflection by adding one claim about how math improved your early plan and one goal for contributing more thoughtfully next time.
