Essential question
Can you feel why some shops make you buy and others make you leave?
What students learn and show
Learn: Layouts can be tested against measurable constraints and observed customer behavior.
Show: Show a layout meets all constraints by measurement and justify one revision with a logged observation.
Objectives
Lay out a small retail space with entry zone, aisles, display fixtures, and checkout
Walk the customer journey and log friction points (pinches, dead ends, blocked sightlines)
Apply measured constraints: 36-inch minimum aisles, clear entry zone, visible checkout
Present the layout as a pitch: where the customer walks, what they see, in what order
Before this lesson students should: Measuring; reading a plan.
Materials and prep
The 1:1 print of a small commercial / retail plan
Painter's tape
Tape measures
Paper fixture footprints (shelving runs, display tables, counter)
Customer-journey log sheets
Prep (about 15 min to print, 35 min to tape)
Lay out a small commercial plan or tape a 20 x 30 ft shell with one entry.
Cut fixture footprints: 4-ft display table, 3-ft-deep shelving runs, 6-ft counter.
Copy journey logs.
Space: A 20 x 30 ft shell.
Grouping: Teams of 3-4.
Ways to run it: Painter's tape on the floor; 1:1 printed floor plan
Lesson procedure
Teacher model: Teacher enters as a customer and narrates: 'First I see... I turn right... I stop here because the aisle pinches.' Logger records each hesitation.
Guided practice: Teams agree the three constraints and measure the entry zone first.
The empty shell: teams walk the bare space and mark the entry 'decompression' zone — the first steps inside where customers orient. Nothing sells there; keep it clear.
Fixture placement: teams tape their layout. Constraints: every aisle 36+ inches (measure it), checkout visible from the entry, at least one path reaching the back wall.
Walk the journey: one teammate enters as 'the customer' and narrates: what do I see first? Where do I turn? Where do I stop? Loggers record every hesitation and pinch.
Swap and shop: teams walk each other's stores and log friction they feel — the designers stay silent and take notes.
One revision: fix the worst logged issue and re-walk.
The pitch: 60 seconds per team — walk us through your customer's journey from door to checkout, pointing at the floor the whole way.
Checks for understanding
Ask: Why keep the area just inside the door clear? Look for: Customers need a few steps to orient; displays there are often walked past.
Ask: Your aisle measures 30 in between fixtures. What must change? Look for: Widen it to at least 36 in.
Ask: Name one friction point and how you fixed it. Look for: A logged issue plus a measured fix.
Exit ticket
List your three constraints and the measurement that shows each is met. Answer: Three constraints with numbers.
Which friction point did you fix, and what changed on the re-walk? Answer: Specific before/after observation.
Scoring: Item 1: 3 points. Item 2: 2 points.
Common misconception
Students may think: If it looks open on the plan, people will flow through it.
Address it: Walk the journey: hesitations and stops show where the layout fails.
Supports and extensions
Learning support: Provide a starter layout with the counter and one shelving run pre-placed; the customer-walk narrator role is scripted with prompts.
Multilingual learners: Journey logs use symbols (eye = 'I see', hand = 'I touch', X = 'I'm stuck'); the pitch may be a walked demonstration.
Mobility and access: Journeys can be rolled or narrated with a token on a tabletop plan; testing against constraints stays the goal.
Extension: Give each team the same product list and compare layouts. Research question: why do some grocery stores put everyday items toward the back? Find a source before deciding.
Transfer task: Map the customer path in a store you know and suggest one change.
Spaced review: Next unit: critique a photo of a store entrance using today's constraints.

Why this approach
In a navigation experiment, adults who physically walked a room-sized virtual space searched it almost perfectly (about 90% of trials), while people using a desktop display or only turning managed under half that rate. Limit: An adult virtual-reality study of search efficiency, not a classroom or design-learning study.
