S1 Geography — Land Use and Urban Development in Hong Kong: Lesson-Prep Guide for Tutors (45-minute flow, scripts, common errors)

2026-11-12

Tutor lesson-prep guides · Secondary Geography

Students label any empty-looking patch as open space and then divide population by the whole district. This lesson binds classification, percentages, density and conflict to one four-square-kilometre sample district so the same numbers carry all four ideas.

Objectives — Students can: (1) sort land into residential, commercial, industrial, open space and roads using the legend only, and say why personal impression is not allowed; (2) convert each area into a percentage and check that the six figures total one hundred per cent; (3) compute population density using residential land only, and explain why the district area is the wrong denominator; (4) analyse a land-use conflict in three boxes: who is affected, what the effect is, and what could reduce it, including the cost of that measure.

01 Prerequisites (3-minute check)

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

Skill	Quick check	Pass mark
Area units	How many square metres are there in one square kilometre?	One million; reteach decimal place value if not
Percentages	Write 1.2 out of 4 as a percentage	Thirty per cent; divide first, multiply by 100
Legend and scale	Can you judge land use by what the map looks like?	No: the legend decides, not the impression

02 Lesson flow (45 minutes)

Time	Stage	Tutor does	Student does
0-5 min	Guess then check	Ask for a guess about the area around school, then check the legend	Write the guess down first
5-13 min	Five classes	Show each legend colour with a typical example, write the five names	Fill the colours into the table
13-24 min	Areas to percentages	Model 1.2 over 4 as thirty per cent, then require a total of 100	Compute six cells and total them
24-34 min	Density uses residential land	Model 96,000 people over 1.2 square kilometres as 80,000 per square kilometre	Explain why 4 is wrong
34-40 min	Conflict in three boxes	Use industry next to housing: who, what, how to reduce	Fill three boxes with reasons
40-45 min	Exit check	Collect three answers, mark live, name the act to reteach	Hand in three answers

03 Teaching script (read it out)

Scene 1: Act one: classification is colour matching

“Step one is not judgement, it is matching. The legend gives five colours: residential yellow, commercial red, industrial purple, open space green, roads grey. A patch that looks like a park but is keyed industrial is industrial. Why so rigid? Because planning figures exist to be compared between districts, and impressions cannot be compared. Fill the table first, explain afterwards.”

Match the legend, not your impression.

Scene 2: Act two: percentages must total one hundred

“One action only: the class area divided by the total, times one hundred. Residential is 1.2 over 4, which is 0.3, so thirty per cent. The six figures must total one hundred. If they do not, you copied a cell wrong or skipped one. That check is free and takes thirty seconds, so do it on every question. A pie chart is the same information turned into degrees: thirty per cent is 108 degrees, because 360 times 0.3 is 108.”

Divide by the total, times one hundred, six cells total one hundred.

Scene 3: Act three: density from housing, conflict in three boxes

“Density is population divided by residential land, not by the whole district. People live on residential land; adding parks and roads pushes the figure down artificially and makes two districts impossible to compare. 96,000 over 1.2 gives 80,000 people per square kilometre. For conflict, always write three boxes: who is affected, what the effect is, and how to reduce it. Three boxes with reasons beat one long sentence, and a measure without its cost is only half an answer.”

Density divides by housing; conflict needs three boxes.

04 Question types and worked steps

Type	Example	Steps	Answer
Classifying land use	Sort the six parcels in the sample district into five classes and give the total area.	(1) Match each parcel to a legend colour (2) name the class (3) add parcels of the same class (4) check the total of 4 square kilometres	Residential 1.2, commercial 0.3, industrial 0.5, open space 0.4, roads 0.6, other 1.0, total 4 square kilometres
Percentages	What percentage of the district is residential?	(1) 1.2 divided by 4 (2) equals 0.3 (3) multiply by 100 (4) check the total against 100 per cent	Thirty per cent; the six classes total 30, 7.5, 12.5, 10, 15 and 25, which is 100
Population density	Population 96,000, residential land 1.2 square kilometres. Find the density.	(1) Take residential land only (2) divide 96,000 by 1.2 (3) get 80,000 (4) state the unit	80,000 people per square kilometre
Conflict analysis	An industrial estate sits next to housing. What problems arise and how can they be reduced?	(1) Name who is affected (2) name the effect: air, noise, traffic (3) give one workable measure (4) state its cost	Residents face air and noise; a buffer strip plus limits on night work helps, but the strip uses land

Sanity check (teach this): Consistency check: (1) the class areas must add up to the total of four square kilometres. (2) The percentages must add up to one hundred; 7.5 and 12.5 must not be rounded to 8 and 13. (3) The density denominator is residential land; using the district area gives 24,000, which is obviously too low and signals the error immediately. (4) Built-up land, meaning residential plus commercial plus industrial, is fifty per cent, and that figure should be quotable. (5) A conflict answer needs all three boxes, and any measure must carry its cost.

05 Independent practice (3 questions)

Question	Answer	What to watch
Using the sample district, find built-up land as a percentage of the district.	1.2 plus 0.3 plus 0.5 is 2.0, divided by 4 gives 0.5, so fifty per cent	Whether the areas are added before dividing
If residential land grows to 1.5 square kilometres with the same population, what happens to density?	96,000 divided by 1.5 equals 64,000 per square kilometre, so density falls	Whether the student states that a larger denominator lowers density
Thirty per cent on a pie chart is how many degrees?	360 times 0.3 equals 108 degrees	Whether 360 rather than 100 is used

06 Common mistakes and what to say

Mistake	Student writes	Say this
Density from the whole district	“96,000 divided by 4 equals 24,000 people per square kilometre”	“Divide by residential land only. People live in housing, not in parks or on roads. Using 4 makes the density look far too low.”
Percentages that total 101	“30 plus 8 plus 13 plus 10 plus 15 plus 25 equals 101”	“Do not round 7.5 up to 8 or 12.5 up to 13. The six figures must total one hundred; if they do not, a cell is wrong.”
Empty land called open space	“This brown patch is a park”	“If the legend says industrial, it is industrial. Looking like a park does not count; classification follows the legend.”
Conflict answered with a wish	“The government should plan better to reduce the impact.”	“Three boxes: who is affected, what the effect is, how to reduce it. Name the measure and its cost, such as land taken by a buffer strip.”

07 Homework (paper, section and question numbers)

Secondary Geography chapter index — All chapters for the subject; the two S1 chapters work in order
Lesson-prep master index — Other subjects show the same data-response structure
Redo this lesson — Take a land-use map of your own district: classify five classes, total the percentages to 100, compute density from housing, and write one conflict in three boxes

08 Exit check (last 5 minutes)

Question	Answer	Decision
What is the denominator for population density?	Residential land, not the whole district	Whole district means reteach act three
What must the six percentages total?	One hundred per cent	Unable to answer means repeat the check in act two
What are the three conflict boxes?	Who is affected, what the effect is, and how to reduce it with its cost	A measure alone means return to the three-box table

09 Tutor FAQ

Must S1 students memorise Hong Kong land-use shares?

No, the classes and the method are what matter. The sample district trains the method; the paper supplies its own figures, and the same steps apply.

Percentages or pie charts first?

Percentages first. A pie chart is just percentages multiplied by 3.6 to give degrees, and teaching it first leaves students drawing instead of dividing.

What if a student cannot suggest a measure?

Offer three directions: separate (buffer strip), restrict (operating hours), compensate (better facilities). Pick one, then add a concrete action and its cost.
