Essential question
How do you turn the size and layout of a home into a defensible price — and then sell it?
What students learn and show
Learn: Price per square foot links area to value; comparables give a range, not one right answer.
Show: Compute a defensible price range from an area and comparable data, and justify the midpoint choice.
Objectives
Measure and total the area of a floor plan
Apply comparable price data to estimate value
Justify a listing price with a chosen comparable
Pitch a home by walking a buyer through it
Before this lesson students should: Area of rectangles; multiplying large numbers; percent.
Materials and prep
The 1:1 print
Tape measures
Calculators
A comparable-sales sheet (teacher provides current local $/sq ft data)
Recording sheets
Prep (about 15 min to print, 40 min to tape)
Pull 3 current local comparables (price and finished square feet).
Lay out the print or tape 3-4 rooms.
Copy the price sheet.
Space: A house plan or 3-4 taped rooms.
Grouping: Teams of 3-4.
Ways to run it: Painter's tape on the floor; 1:1 printed floor plan; Paper only (no floor space needed)
Lesson procedure
Teacher model: 'Comps: $160, $175, $190 per sq ft. Our house: 1,500 sq ft. Low = $240,000, mid = $262,500, high = $285,000.' Note that listings use finished living area, which includes walls and halls, so summing room interiors comes out smaller.
Guided practice: Teams compute their low price together and check units.
Teams tape-measure and compute the area of each printed room, then total the plan.
Apply the comparable sheet's $/sq ft range to price the house — low, middle, and high.
Justify one number: which comparable does this plan most resemble, and why? Write the one-paragraph rationale.
The pitch: one student walks a 'buyer' through the plan at a calm pace, selling the layout room by room.
Class vote: which pitch would win the listing — and which priced it most defensibly?
Checks for understanding
Ask: A house totals 1,800 sq ft and comparables run $150/sq ft. What is the price at that rate? Look for: $270,000.
Ask: Why present a price range instead of a single number? Look for: Comparables vary; a range shows the judgment behind the price.
Ask: Why might your measured room total be smaller than the listed square footage? Look for: Listings use finished area to outside of walls; room interiors leave out walls, halls and closets you did not measure.
Exit ticket
Comps: $140, $155, $170 per sq ft. Area 1,200 sq ft. Give the low, middle and high prices. Answer: $168,000; $186,000; $204,000.
Which comp would you weight most, and why? Answer: A reason tied to similarity (size, location, condition).
Scoring: Item 1: 3 points. Item 2: 1 point.
Common misconception
Students may think: Adding up room areas gives the official square footage.
Address it: Measurement standards for listing area include wall thickness and halls; room interiors undercount.
Supports and extensions
Learning support: Assign one room and a pre-formatted area worksheet; provide the comparable figure.
Multilingual learners: Pitch from a sentence-frame script; pre-teach 'listing', 'comparable', 'square foot'.
Mobility and access: Pitches can be delivered seated with a pointer, in writing, or recorded; computation stays the same.
Extension: Adjust price for a premium feature (extra bath, open plan) and defend it. Challenge: two teams price the same home from different comparable sets and reconcile the gap.
Transfer task: Compute rent per square foot for two apartment listings and compare value.
Spaced review: A month later: 'A 900 sq ft condo sold for $171,000. Price per sq ft?' ($190)

Why this approach
Drawing on 50 years of longitudinal data, spatial ability is an independent, underused predictor of STEM entry and achievement. Limit: Correlational. It shows spatial ability matters; it does not show that this lesson changes it.
