DSE Geography — Urban Land Use and Land Use Conflict: Lesson Prep Guide (Tutor Edition)

2026-11-03

Tutor lesson-prep guides · Secondary Geography

Students repeat that city-centre land is expensive yet cannot draw a bid-rent curve or explain why a redevelopment scheme divides a community. Two intersecting lines produce the zone boundary, and real percentages and densities explain the conflict.

Objectives — Students will be able to: (1) solve 120 minus 8d against 60 minus 2d to place the boundary at 10 km with rent 40, explaining why that point separates commercial from residential use; (2) compute density of 5000 people per square kilometre from 250000 people over 50 square kilometres and link density to transport and service demand; (3) use five land use shares (residential 55, commercial 8, industrial 7, green 20, transport 10 per cent) to analyse stakeholder conflict in urban renewal and defend a compromise.

01 Prerequisites (3-minute check)

If any of these fails, fix it before the lesson starts.

Skill	Quick check	Pass mark
Urban functions	Three features of a CBD?	Tall buildings, high density, commerce and finance
Accessibility	What happens to accessibility with distance?	It falls as travel time and cost rise
Density	How is density calculated?	Population divided by area, in square kilometres
Graph reading	What does an intersection mean?	Both values are equal there, usually a boundary

02 Lesson flow (60 minutes)

Time	Stage	Tutor does	Student does
0–10 min	Rent warm-up	Write centre and fringe rents and ask for the trend	Describe the fall with distance
10–22 min	Draw both lines	Plot 120 minus 8d against 60 minus 2d on one grid	Draw two downward lines
22–32 min	Find the crossing	Set the two expressions equal and solve	10 km and 40
32–44 min	Density and zones	Compute density from 250000 over 50, then read the land use shares	5000 per square kilometre
44–52 min	Question drill	One calculation, one graph, one conflict, one proposal item	Work independently for eight minutes
52–60 min	Exit check	Mark three written items on the spot	Complete independently

03 Teaching script (read it out)

Scene 1: Two straight lines in competition

Commerce earns more per square metre and can bid higher, but it depends on footfall and loses value quickly with distance, so its slope is minus eight. Housing needs space and its rent falls slowly, slope minus two. Setting 120 minus 8d equal to 60 minus 2d gives d equal to 10 km at a rent of 40. Inside that ring commerce outbids housing, outside housing wins: zoning is arithmetic, not official whim.

Ask students: why is the commercial line steeper?

Scene 2: Density needs one unit

250000 people over 50 square kilometres gives 5000 per square kilometre. Using hectares inflates the answer a hundredfold; mixing people with a hectare figure deflates it. Density drives bus frequency, school and clinic provision, and explains redevelopment pressure in old districts. Floor area matters too: twenty storeys at 800 square metres each yield 16000 square metres, so height multiplies the same plot.

Ask students: what goes wrong in a city if density is miscalculated by a hundredfold?

Scene 3: Conflict needs named stakeholders

Urban land splits roughly into residential 55, commercial 8, industrial 7, green 20 and transport 10 per cent. In renewal, developers count floor area, residents count rehousing and compensation, small shops count rent, heritage groups count old buildings, and transport planners count road capacity. No single scheme pleases all five, so answers must state who gains, who loses and what compensation applies, not that government should balance interests.

Ask students: which two stakeholders must appear in any acceptable conflict analysis?

04 Question types and worked steps

Type	Example	Steps	Answer
Calculation	Intersection of two bid-rent curves	Set equal, solve for distance, substitute for rent, state the meaning	10 km at 40
Graph reading	Identify each zone from a bid-rent diagram	Compare slopes, locate the crossing, assign use with reasons	The steeper line holds the centre
Conflict analysis	Five stakeholders in urban renewal	List them, state goals, state gains and losses, propose compensation	One concrete point per stakeholder, no slogans
Proposal	Traffic and green space in a dense old district	Support need with density, give two measures, state the limits	At 5000 per square kilometre, vertical greening and bus lanes are defensible

Sanity check (teach this): Sanity check: two straight lines cross once, so a negative distance is an algebra error; the commercial slope is always steeper; density carries the unit people per square kilometre; the shares total 100; balancing interests is not analysis unless gains and losses are named.

05 Independent practice (3 questions)

Question	Answer	What to watch
Solve 120 minus 8d equals 60 minus 2d	10 km	Check constants are collected before dividing
250000 people over 50 square kilometres: density?	5000 per square kilometre	Check hectares are not used
Twenty storeys at 800 square metres: total floor area?	16000 square metres	Check storeys are multiplied

06 Common mistakes and what to say

Mistake	Student writes	Say this
Reversing the slopes	Housing rent falls faster than commercial rent	Commerce needs footfall, so its bid falls faster and its line is steeper.
Calling the crossing the highest rent	The intersection is the most expensive spot	The crossing is where two uses bid equally, so it is the boundary; the peak is at distance zero.
Dropping the density unit	The density is 5000 people	Density is people per square kilometre; without area it is a count.
Slogans instead of analysis	Government should balance all interests	Name what developers, residents, shops and heritage groups each gain and lose.

07 Homework (paper, section and question numbers)

Secondary Geography chapter index — Copy three key terms from the urban chapter with one definition each
Population (S4 chapter) — From the index, compare the population chapter density figures with this lesson
Weather and climate (S4 chapter) — Use the weather chapter to explain the urban heat island in a dense district

08 Exit check (last 5 minutes)

Question	Answer	Decision
What does a bid-rent crossing mean?	Two uses bid the same rent, so it is the zone boundary	If the highest rent: reteach the crossing
250000 people over 50 square kilometres: density?	5000 per square kilometre	If the unit is dropped: reteach density
Which two stakeholder gains and losses must be named?	Residents and developers, ideally with shops or heritage groups	If only government: reteach stakeholder analysis

09 Tutor FAQ

Which year level is this for?

S4 urban studies; S6 can reuse it for land conflict and sustainability.

Is 60 minutes enough?

Yes; if algebra is weak, spend five minutes on rearranging and move the proposal to homework.

Is there practice attached?

The homework links to site chapter pages with answers under independent practice.
