🧩 Scaled Park Draft Build

Product Assessment Reflection Core Content Community Partners Essential Question Critique and Revision Submission Required Grading Required

Teams use their How Might We statement, site map, measurement cards, grid paper or model pieces, rulers, and calculators to produce a first draft of a welcoming community space. The draft must include a scaled sketch or small model, at least three labeled unit rates, two proportional calculations, and one multistep cost or materials estimate tied to real constraints from the planner, engineer, or architect materials. Midway through work time, students pause for a quick peer-feedback round: each team gives one sticky-note suggestion about unit rates or proportions to 2 peers, receives feedback, and revises at least one design feature before finishing their draft board.

#	What teachers do
1	Launch the draft build by introducing the design goal, posting the essential question, reviewing the required draft components, and having teams assign roles such as scale checker, calculator, recorder, and materials manager while they examine the site map and community partner data. (8 min)
2	Teams analyze site maps, measurement cards, and planner, engineer, or architect constraints to choose a workable scale, identify needed dimensions, and plan which features will best serve a welcoming community space within the available area and material limits. (10 min)
3	Teams create the first version of their scaled sketch or small model using grid paper or model pieces, label at least three unit rates, complete two proportional calculations, and solve one multistep cost or materials estimate using rational number operations to justify layout decisions. (18 min)
4	Pause for a gallery walk in which each team visits two drafts, leaves one sticky-note suggestion about unit rates or proportions for each peer team, and also notes one academic strength and one social skill they notice in their own work and others' work. (8 min)
5	Teams review feedback, discuss which suggestion is most useful, revise at least one design feature, and clearly mark the before-and-after change on the draft board or model with a short explanation of how the revision improved fairness, usability, or fit. (9 min)
6	Hold quick comparison conferences where each team briefly presents the original idea, the revision they made after feedback, and the math reasoning behind the change, then students record a short audio reflection and complete an exit chart claim about how math improved the plan plus one goal for stronger contribution next time. (7 min)

Preparation (8 items)

Print and organize site maps, measurement cards, material cost data, and realistic planner, engineer, or architect reference materials for each team.
Prepare team supply bins with grid paper, rulers, calculators, pencils, colored pencils, sticky notes, tape, and any model-building pieces to support either sketching or small model construction.
Create and display a draft checklist that includes: scaled sketch or model, at least three labeled unit rates, two proportional calculations, one multistep cost or materials estimate, and one visible revision after feedback.
Set up a sample scale conversion example and one modeled unit-rate example students can reference if they get stuck without turning the activity into direct instruction.
Post the essential question and a simple feedback sentence frame such as 'Check the unit rate for ___ because ___' and 'Your proportion might be stronger if ___.'
Prepare gallery walk spaces so teams can leave materials visible, rotate easily, and place sticky notes directly on draft boards or beside models.
Prepare a brief comparison conference protocol and an exit chart template with two prompts: one claim about how math improved the plan and one goal for more thoughtful team contribution next time.
Test audio reflection tools or designate a simple recording option so students can quickly capture a short reflection without losing work time.

Student-facing instructions

You will work with your team to create a first draft of a scaled neighborhood park plan that responds to the site and community constraints in your materials. Use your How Might We statement, site map, measurement cards, ruler, calculator, grid paper, and/or model pieces. Your task is to build a sketch or small model that uses one consistent scale and shows how your park will be welcoming, useful, and realistic. As you work, you must include at least three labeled unit rates, two proportional calculations, and one multistep cost or materials estimate. Divide team roles so everyone contributes to measuring, calculating, recording, and checking the design. Midway through class, you will participate in a gallery walk: visit two teams, leave one sticky-note suggestion about unit rates or proportions for each, and notice one academic strength and one social skill in the work you see. Then return to your own draft, review the feedback, and revise at least one feature of your design. Mark what changed and be ready to explain how the revision improved the space. At the end, your team will give a short before-and-after comparison conference, record a brief audio reflection about how feedback changed your math or design choices, and complete an exit chart claim and goal.

Success criteria

Your team is successful when you have completed a scaled sketch or small model using a consistent scale; labeled at least three correct unit rates connected to the design; shown two proportional calculations; solved one multistep cost or materials estimate using rational number operations; used site and materials data from the community planning resources; given one sticky-note suggestion to each of two peer teams about unit rates or proportions; identified one academic strength and one social skill during the gallery walk; revised at least one design feature based on feedback; clearly showed the before-and-after change on your draft; explained in a brief conference how the revision improved fairness, usability, or fit; recorded a short audio reflection; and completed an exit chart with one math-based claim and one collaboration goal.

Facilitator notes

Keep the pace brisk and visible with a timer because this lesson includes drafting, critique, revision, reflection, and sharing in one class period. Front-load the nonnegotiables by posting the checklist and reminding teams that the goal is a justified first draft, not a polished final product. Encourage adolescent engagement by letting teams choose whether to work as a sketch or model group and by assigning roles that rotate naturally during work time. Monitor early for scale consistency; a common pitfall is students starting to draw features before agreeing on a scale. Another common issue is labeling answers without showing how the unit rates or proportions were calculated, so prompt teams to annotate their math directly on the draft board. During the gallery walk, require feedback to be specific and math-focused rather than preference-based. If teams struggle to give quality critique, point them to the sentence frames. Differentiate by offering pre-highlighted measurement data, a suggested scale option, or partially set-up calculation organizers for students who need support. Extend learning for advanced students by asking them to compare two possible layout options using equivalent ratios or justify why one plan is more efficient or fair. Support collaboration by checking that all voices are included before revisions are finalized. In the final conference, keep shares to about one minute per team and focus on what changed, why it changed, and which calculation supported the revision.
