Secondary 2 is a delightful turning point for a curious young economist. Prices, which once seemed like numbers attached to things, become little stories. Why can the same snack cost more next year? Why might one seller put prices down while another raises them? And why does a family sometimes feel a squeeze even when an impressive headline says inflation is slowing? A well-taught Punggol tutorial turns those questions into careful observation rather than alarm.
The subject focus is inflation, the cost of living in Singapore, price changes, the Consumer Price Index (CPI), purchasing power, demand and supply, and household budgeting. Secondary 2 students should learn that one expensive item is not the same as general inflation, that inflation slowing does not necessarily mean prices are falling, and that percentages require a clear comparison period. These lessons are a lower-secondary economic-literacy enrichment progression, not a universal standalone Secondary 2 Economics school syllabus.
Is Secondary 2 Economics a formal examinable subject?
In Singapore, Economics is not a standalone examinable subject universally prescribed for Secondary 2. Economic ideas can be explored through humanities, financial literacy and related learning. The 2027 Singapore-Cambridge SEC G3 Economics syllabus K343 applies to an upper-secondary subject that SEAB marks as available only through approved schools. A parent must check the child’s own school before assuming there is an Economics examination pathway.
Our guide describes a quality Secondary 2 Economics tuition or enrichment lesson that could support Punggol families. It does not assert a particular provider’s Economics class schedule, class size, current price, tutor credentials or guaranteed result. In this year the priority is forming accurate explanations of everyday market and household changes, not copying advanced economics paragraphs from a course the student may never take.
What changed from Secondary 1?
Secondary 1 began with scarcity, opportunity cost, needs versus wants and budgeting. These ideas are deeply personal: one learner has a limited amount of money or time and chooses how to allocate it. Secondary 2 shifts attention outward. A supermarket, a household, a school canteen and a business each respond to wider circumstances; their decisions interact.
A child may already say, “I cannot afford that now.” Secondary 2 invites the next question: “Why did the price change, how can I check, and who is affected differently?” The tutor should revisit first-year budget skills throughout the year so Economics grows cumulatively rather than becoming a stack of disconnected new definitions.
What is inflation, in one clean sentence?
Inflation is a sustained rise in the general level of prices over time, often measured by a consumer price index. “General” matters: it is not the story of one product. “Over time” matters: comparison periods need to be named. A rise in the cost of one service may be significant to a household without itself showing the economy-wide inflation rate.
For a student, this is a chance to practise disciplined language. Say “this particular item’s price has risen” when discussing one price. Say “consumer price inflation was positive over the measured period” only when describing an appropriate index or credible general measure. The precision may sound small, but it prevents misleading claims later.
Inflation falling does not mean prices have fallen
Imagine a fictional price index rising from 100 to 110 and then to 115.5 in successive years. The first annual rise is 10%; the second annual rise is 5%. Inflation has slowed from 10% to 5%, but the price level has still increased. People may continue paying more even while the rate of increase falls.
A tutor can write the distinction in everyday language: “The car is still moving forward; it has simply slowed down.” This analogy is helpful if students also examine the actual numbers. An analogy without a calculation can create confidence without accuracy; a calculation without a clear explanation can create fear of Mathematics.
Disinflation, deflation and a price reversal
Disinflation means inflation remains positive but decreases in rate. Deflation refers to a decline in the general price level, corresponding to a negative inflation rate for the period. A fall in the price of tomatoes is not necessarily economy-wide deflation, just as a fall in one subscription fee does not prove everything is becoming cheaper.
These labels are useful as vocabulary, but they should not become a race to memorise technical words. Students first calculate percentage changes, identify the relevant index and explain what the figures mean. The formal terminology then becomes a shortcut for a concept they actually understand.
Cost of living is related to inflation, not identical to it
Cost of living describes the expenditure needed to support a particular standard of living in a place. Inflation describes a rate of change in a general price level. Two households may face very different practical experiences because their spending patterns differ: transport, food, childcare, housing, healthcare, learning needs and discretionary activities have different weights.
Suppose household A spends a larger share on commuting while household B works mainly from home. The same transport-price rise affects their immediate budgets differently. This is a thought experiment, not a claim about actual Punggol households. A good tutor teaches young people to respect differences rather than assuming every family shares one financial story.
What is the Consumer Price Index?
Singapore’s Department of Statistics describes the Consumer Price Index as a measure of average price changes over time for a representative basket of goods and services commonly purchased by resident households. The basket contains many categories, not just the products a student happens to notice at the shops.
As of October 2026, SingStat identifies 2024 as the current CPI base year, with the 2024 index set to 100. This is a methodological detail worth teaching accurately, not a number students should cling to forever. Base years and weights can be revised as spending patterns change; the relevant official page should be checked when preparing future lessons.
Why basket weights matter
A weighted index gives greater influence to categories that account for a larger share of household spending. Imagine a toy basket containing food with a 50% weight, transport with a 30% weight and recreation with a 20% weight. If the component price indices change differently, the weighted result is not the unweighted average of the three changes.
To illustrate, if food prices rise 4%, transport 2% and recreation 10%, an elementary fixed-weight calculation gives 0.50 × 4% + 0.30 × 2% + 0.20 × 10% = 4.6%. The result depends on the hypothetical weights and simplifying assumptions. It is not a published Singapore inflation statistic.
Reading an index instead of a rumour
Students often encounter posts online claiming that “everything is twenty per cent more expensive.” A good tutor asks the learner to identify what is being compared: which basket, which month or year, which group of households and which source? The phrase may reflect a real feeling while failing as a general statistical claim.
An official CPI series is more trustworthy for studying consumer-price inflation, but even it does not perfectly replicate every individual family’s expenses. Statistical measurement offers a standardised comparison, not a guarantee that everyone experiences the same impact. That nuance is a wonderful bridge to source evaluation in Social Studies.
Nominal versus real purchasing power
If a student’s hypothetical allowance remains S$40 a week while the prices of what they regularly buy rise, the same money generally buys less of that fixed selection of goods. This is a simple way to understand purchasing power. Nominal money is the amount written in dollars; real purchasing power asks what those dollars can obtain.
Suppose the price of an illustrative basket rises from S$20 to S$22. S$44 now buys two such baskets, just as S$40 previously bought two; a 10% rise in the budget matches a 10% rise in this basket price. A tutor should clarify that this is a simplified one-basket demonstration, not a precise real-wage calculation for an entire country.
How demand can influence a price
When more consumers are willing and able to buy at each possible price, demand increases, other things equal. If supply does not expand to match, a higher equilibrium price may result. This is a useful conceptual bridge from Secondary 1, but the student should not claim that demand always increases whenever a queue appears.
A queue can form because one worker is absent, because service has slowed, because people arrived simultaneously or because actual demand increased. Good Economics requires an explanation appropriate to the evidence. The tutor can show two possible stories and ask what observation would distinguish them.
How supply and costs influence a price
A rise in the costs of materials, transport, rent or labour can reduce a firm’s willingness to supply at a given price, other things equal. In a simple market model, this may place upward pressure on equilibrium price. The actual outcome depends on competition, consumer responses, business choices and the relevant market.
Students should be cautious about blaming any single cause without evidence. An observed price rise at a fictional bakery is not proof that flour costs rose. A well-designed lesson asks for plausible mechanisms, then separates possible explanation from verified explanation.
Why a price can fall even while general inflation is positive
Prices in different markets do not move together perfectly. An individual product might become cheaper because of improved production, competition, a temporary promotion or reduced demand, while a broader consumer-price index continues rising. A student should recognise that this is not a contradiction.
Similarly, some goods can become more expensive despite a general index showing modest inflation. Averages compress diverse experiences. The best young economist learns to unpack them before drawing conclusions.
A Secondary 2 tutorial’s ideal rhythm
Begin with one reliable data point or clearly fictional scenario. Ask the student to state what changed using the correct units. Then ask for a possible cause, a competing explanation and one consequence for a specific person or business. Only after the learner has tried should the tutor formalise the vocabulary.
The lesson needs a transfer task: if the learner understood an annual CPI comparison, can they analyse a fictional monthly price series? If they understood a buyer, can they reason from a seller’s viewpoint? Finally, they write a three- or four-sentence conclusion with an explicit qualification.
Worked case 1: a S$2.50 snack becomes S$2.80
A fictional snack rises from S$2.50 to S$2.80. The increase is S$0.30. Dividing the change by the original S$2.50 gives a 12% price increase. A student who divides by S$2.80 is answering a different percentage question.
Now ask whether the 12% change proves Singapore’s inflation rate is 12%. It does not. One product’s price is not the full CPI basket. The student should write both facts distinctly: “The snack price increased by 12%, but that single observation cannot determine general consumer-price inflation.”
Worked case 2: a fictional CPI series
Suppose an index reads 100 in Year A, 104 in Year B and 107.12 in Year C. The Year A to Year B inflation rate is 4%. The Year B to Year C rate is 3%, because 3.12 divided by 104 equals 0.03.
The tutor asks two questions. Did prices generally fall in Year C? No; the index rose. Did inflation slow? Yes, from 4% to 3%. The distinction becomes memorable because the learner has calculated it, explained it and noticed why everyday language can mislead.
Worked case 3: two families, two baskets
Household A hypothetically allocates 40% of spending to Category X and 60% to Category Y. Household B allocates 70% and 30% respectively. If X rises by 8% and Y by 2%, a simple fixed-weight calculation gives household A a 4.4% increase and household B a 6.2% increase.
The tutor should note that real official indices have a much richer methodology and many categories. The lesson goal is to explain why expenditure weights influence experiences. It should not label either family as careless or invent their income or housing circumstances.
Worked case 4: a cheaper package with a catch
A fictional item sells for S$6 per 500 g or S$8.40 per 800 g. The first costs S$1.20 per 100 g; the second S$1.05 per 100 g. For a household that uses the entire quantity, the second has a lower unit price.
What if half the larger pack is wasted? Then unit-price superiority does not settle the real choice. The student should compare likely usable quantity, storage and household preferences. This extends Secondary 1 budgeting into the more subtle idea of effective cost.
Worked case 5: a small price change across a month
A fictional commuter incurs a S$3 transport expense twenty times each month. That component totals S$60. If the unit cost increases to S$3.20 while the number of trips remains the same, the total becomes S$64, an increase of S$4.
The point is cumulative impact under stated conditions. It does not claim a real fare change. The tutor can now ask what happens if the number of trips changes, and why a person with different travel needs experiences a different budget impact.
Worked case 6: budget revision after price increases
Suppose a student planned S$15 for necessities, S$10 for optional purchases and S$5 for saving each week, fully using a S$30 allocation. Necessary costs rise to S$17.50. The old plan now totals S$32.50 and is infeasible without change.
A strong response protects essentials, then considers whether to reduce optional expenditure, adjust the savings schedule or revisit the assumptions. The tutor should not insist that the savings amount must always stay fixed if doing so would sacrifice important needs.
Worked case 7: the weekend stall and input costs
Consider a fictional food stall whose packaging, ingredients and electricity costs all rise. The owner faces a choice among adjusting price, changing operations, accepting a lower margin or finding different suppliers. None is automatically best.
Students might calculate a price change but must also discuss whether customers will respond. A rise in input costs can affect supply; it does not guarantee an identical percentage rise in the selling price. Competition and customer preferences matter.
Worked case 8: two shops’ different promotions
Shop A advertises an item at S$18 after a S$2 discount. Shop B offers the same item at S$17.50 but charges S$2 delivery. If the student can collect from Shop A at no extra cost, A is S$18 and B is S$19.50 delivered. The apparent cheaper label does not produce the cheaper final bill.
The tutor asks for a like-for-like comparison including final cost and convenience. A learner who can find missing charges is building practical market literacy. All prices are fictional; no current Punggol retail claim is made.
Worked case 9: the price of one imported item
A fictional imported product costs 10 foreign-currency units. At a simplified exchange rate of S$1.40 per unit, its currency-converted price is S$14 before other costs. At S$1.30, the converted amount is S$13. The exercise illustrates why an exchange rate can influence import prices.
But retail prices also reflect shipping, rent, taxes, business pricing decisions and the timing of inventory purchases. It would be too simplistic to claim every exchange-rate movement is immediately and fully passed on. The student’s answer should state what has been held constant.
Worked case 10: salary growth and price growth
Imagine a worker’s nominal wage rising from S$2,000 to S$2,100, a 5% increase. If a relevant price index rises by 4%, purchasing power has increased only modestly. The precise ratio in a simplified model is 1.05 divided by 1.04, approximately 1.0096, or about 0.96% real growth.
For Secondary 2, that exact ratio is optional enrichment; what matters is the direction and the distinction between nominal and real change. The tutor should not use this invented figure as evidence about actual wages in Punggol.
Worked case 11: one product gets cheaper
A fictional calculator falls from S$20 to S$18 while a broader hypothetical CPI index rises by 2% over the same comparison period. The calculator price fell by 10%, yet general inflation remains positive. There is no logical conflict.
The learner should now explain why: a price index covers many items, not just the calculator. This is a useful check because students who memorise “inflation means higher prices” sometimes conclude that no price can ever decrease during inflation.
Worked case 12: two differently timed comparisons
A headline says a fictional price index is 3% higher than twelve months ago; a second says it is 0.2% higher than last month. The two measurements use different baselines and periods. They cannot be directly compared as if they described the same change.
Ask the child to underline every time reference and write it in the margin. “Month-on-month” and “year-on-year” are not cosmetic expressions. The period affects what the number says and which questions it can answer.
Worked case 13: the price ceiling thought experiment
Suppose a hypothetical product is very popular and a rule prevents sellers from charging above a low fixed price. The tutor asks whether every buyer will therefore be able to purchase it. The answer depends on supply and demand. A price ceiling set below market equilibrium can create shortages in the simple model.
This is an optional conceptual preview, not a claim about a policy currently used for a particular Punggol good. The student should learn to ask whether a price rule changes the availability of a product, not just the amount displayed on a label.
Worked case 14: a longer school-holiday queue
A student observes that a fictional café has a long queue during a school holiday. They conclude, “Demand has increased, so prices must rise.” The tutor challenges two steps. The queue may have several causes, and even if demand has increased, the seller may keep its price unchanged.
The improved answer is conditional: “Higher demand could contribute to longer queues and may put pressure on price if supply is constrained; however, we need evidence and the business may respond in other ways.” That distinction between a model and a prediction is precious.
Worked case 15: comparing two years of spending
A household’s fictional spending rises from S$800 to S$880 per month. This is a 10% increase in nominal spending. But spending more does not automatically show 10% inflation: the family may have bought more items, different items or services of different quality.
A careful tutor asks what quantity and mix were held constant. The learner should be able to say, “The household spent ten per cent more; I cannot attribute the whole increase to inflation from this information alone.”
Worked case 16: different effects of the same change
A fictional bus-service cost increase may concern a commuter differently from a resident who usually walks. A tuition-material price rise might affect a family buying new books but barely affect a family reusing existing materials. Students need not assume the impacts are equal.
The learning objective is not merely “inflation is bad”. It is to identify who bears costs, who might benefit, what alternatives exist and what evidence is needed. Perspective-taking complements economic literacy and strengthens humanities discussion.
Worked case 17: a sale following a price rise
A fictional product rises from S$50 to S$60, then receives a 10% discount. The discounted price is S$54, still S$4 higher than the original S$50. Ten per cent off S$60 is S$6, not S$5, because the base has changed.
A student should practise writing the order of operations and dates before calculating. This is a wonderful test of whether they are reasoning about percentage bases rather than guessing from advertising language.
Worked case 18: the case of a missing data label
The tutor presents a fictional bar chart with values 100, 104 and 109, but no unit or period label. The student is asked to explain the trend. A tempting response is “Prices rose nine per cent in two years.” Yet without units or dates, that claim is unjustified.
The most sophisticated beginner response is to request the missing labels. Students should learn that refusing to invent context is a form of intelligence, not a failure to provide an answer.
The correct approach to Singapore inflation
Singapore’s Monetary Authority conducts monetary policy with an exchange-rate-centred framework, managing the Singapore dollar nominal effective exchange rate against a trade-weighted basket of currencies. This differs from describing MAS as setting one domestic policy interest rate in the manner associated with some other central banks. Details can be explored progressively rather than imposed on thirteen- or fourteen-year-olds in full.
For Secondary 2, the important observation is that Singapore buys and sells extensively with the rest of the world and that changes in exchange rates can affect the cost of imports. Later, formal G3 students can analyse monetary policy more carefully. A quality local article should reflect Singapore’s actual institutions.
Why reading official sources matters
The Singapore Department of Statistics explains CPI methodology, including the basket, weights, base year and methods of comparison. MAS explains inflation and its monetary-policy framework. These are preferable to a viral chart without a source. Students should learn to find the date, unit and underlying definition before accepting any dramatic statistic.
A tutor can occasionally show a small excerpt from an official source and ask the student to translate it into ordinary language. However, a single official table can be enough for one lesson. Flooding a lower-secondary learner with national accounts will not produce deeper understanding merely because the material looks sophisticated.
A five-part diagnostic for Secondary 2
First, ask what “inflation has fallen” might mean and discover whether the learner confuses rate and price level. Second, calculate a simple percentage change and check the denominator. Third, compare two budgets and identify their different spending patterns. Fourth, explain a price rise using more than one plausible economic mechanism. Fifth, interpret a chart with labelled dates and units.
The tutor should build a misconception log: terminology, arithmetic, graph-reading, causation or application. The teaching response is different for each. A child confused by wording needs clearer contrast cases; a child making denominator errors needs structured numerical practice.
The best revision card is a question, not a slogan
Rather than writing only “Inflation = increase in prices”, write: “Can one expensive product prove inflation?” or “Does slowing inflation mean falling prices?” The child answers in one or two sentences with a supporting example. Active retrieval strengthens the ability to use language accurately under unfamiliar circumstances.
A second card might say: “What is the original value when calculating a percentage increase?” A third: “Which household feels the greater impact from a transport-price change, and why might that differ?” These prompts help students apply reasoning rather than simply recite definitions.
From data to explanation: a model paragraph
A strong short paragraph could read: “The fictional index increased from 104 to 107.12, so the annual inflation rate was 3% using 104 as the baseline. Since the index is still higher, the general price level rose even though inflation slowed from the previous year’s 4%. The result describes the index basket, and individual households may experience different spending pressures.”
The paragraph demonstrates definition, calculation, meaning and qualification. The tutor should not require these exact words; it is more important that the child can construct a similar argument from a new table.
A four-week learning progression
Week 1: price arithmetic and vocabulary. Correct percentage bases, distinguish one-item prices from price indices, and revisit basic Secondary 1 budgeting. Use short fictional examples to avoid information overload.
Week 2: basket thinking. Explore fixed baskets, weightings, CPI and why cost-of-living experiences differ among households. Introduce basic chart literacy and source reliability.
Week 3: explanations. Connect buyer behaviour, business costs, demand and supply, the distinction between a mechanism and a verified fact, and simple purchasing-power comparisons.
Week 4: independent transfer. Give a fresh multi-source fictional case. Ask the learner to calculate accurately, present two plausible explanations, identify a stakeholder impact, and write a balanced conclusion.
This is an illustrative tutorial sequence, not a published school calendar or an assertion about the programme timetable of any tuition centre.
How Economics and Mathematics strengthen one another
Percentages, ratios, unit prices, graphs and clear reference periods are essential mathematical tools for understanding prices. A student who cannot calculate a change reliably will struggle to interpret economic news, even if they can memorise correct definitions. The best approach is to integrate arithmetic into a question worth answering.
For example, instead of twenty isolated percentage sums, ask how a price changed and whether the change is large relative to the correct baseline. The meaning checks the Mathematics and the Mathematics checks the explanation. That loop is an effective foundation for later diagram and data-response work.
How Economics and Social Studies strengthen one another
A headline is not an argument. Students should ask who produced the information, for what purpose, at which date and with what evidence. Different households, firms and governments face different constraints; learning to recognise these perspectives makes discussion more humane.
A good Economics tutorial does not replace Social Studies and should not make claims about its national examination requirements. It simply borrows sound source-evaluation habits and applies them to prices and markets, respecting the boundaries between disciplines.
How to talk about cost of living without worrying children
Young teenagers hear adults discuss bills, jobs and rising costs. Economic literacy should make these conversations more understandable, not transfer adult anxiety to children. Use fictional data, explain uncertainty and avoid asking learners to disclose family income, debt or private expenditures.
Parents can say, “Prices can change, so families plan and adjust. Our job is to look at information carefully and make appropriate choices.” The goal is practical competence and emotional steadiness, not turning a family dinner into a macroeconomic emergency.
Mistakes that a good tutor must catch
Mistake: inflation and cost of living are perfect synonyms. Repair by comparing a standard price-index change with different fictional household spending baskets.
Mistake: if inflation decreases, every price should fall. Repair with two consecutive positive growth rates and an index that continues rising.
Mistake: one item rises by 10%, therefore CPI rises by 10%. Repair by explaining the many components and weights in a representative basket.
Mistake: the new price is always the denominator. Repair by asking the learner to circle the original reference value before calculating.
Mistake: a queue proves that demand has risen. Repair by listing alternative causes and identifying what additional evidence would help.
Mistake: higher input cost automatically means identical price increases. Repair by discussing competition, firms’ choices and demand responsiveness.
Mistake: two households must have identical inflation experiences. Repair by changing the share each spends on the item whose price changed.
Mistake: an official index proves a personal story false. Repair by distinguishing an aggregate measure from an individual expenditure pattern.
Mistake: a statistic without dates is usable. Repair by withholding a conclusion until the time period and units are clear.
Mistake: Economics is just gloomy news. Repair by showing how data can make plans more realistic and how good decisions preserve joy as well as resources.
Questions parents should ask a prospective tutor
Ask for an example of the difference between “the inflation rate fell” and “the general price level fell”. Ask how the tutor checks percentage calculations, addresses rumours and teaches source literacy. Ask for evidence of a learner solving a fresh problem after correction, rather than only a completed stack of guided exercises.
Check whether tuition is enrichment or preparation for a subject your child actually takes. Confirm lesson arrangements, tutor credentials, fees and learning targets directly. A provider’s Mathematics or English service page is not proof that a particular Economics class currently operates.
Parent FAQ: Is the Consumer Price Index something Secondary 2 pupils must memorise?
Not as a universal standalone Economics syllabus. For enrichment, CPI is a useful illustration of measured price change. Memorising a particular year’s base without understanding a fixed basket is much less important than conceptual accuracy.
Parent FAQ: Why can the cost of living feel high even when inflation is lower?
Prices may still be rising, merely more slowly; previous increases remain in the price level. Personal spending patterns can also differ from the representative CPI basket. Students should learn those distinct explanations before jumping to conclusions.
Parent FAQ: Is every price rise caused by inflation?
No. A particular price may change because of its own market circumstances. Inflation refers to the wider price level, while individual goods and services can move at different rates or in opposite directions.
Parent FAQ: Should children track our actual household finances?
They do not need to. Fictional numbers and privacy-safe public data are sufficient for excellent lessons. Respecting family boundaries is part of good educational practice.
Parent FAQ: Can a young learner study interest rates and exchange rates?
Yes, conceptually, provided explanations fit their readiness. Detailed policy transmission and international accounts belong later. For Singapore, explain that MAS monetary policy is centred on the exchange rate, not a copied foreign interest-rate model.
Parent FAQ: Does understanding inflation improve writing?
It can improve precision in explanations, causal logic and qualifications. Asking a child to name the time period and alternative explanation makes many humanities and expository answers stronger.
Parent FAQ: What if my child is weak at percentages?
Teach the reference base, units and a repeatable calculation process first. Use concrete numbers, then gradually increase complexity. Strong Economics teaching includes targeted numeracy repair.
Parent FAQ: Do we need expensive current-price databases?
No. Simple invented tables work for concepts; accessible official SingStat and MAS explanations work for real background. The tutor should label fiction and fact clearly.
Parent FAQ: Does slower inflation guarantee improvement in living standards?
No. Living standards involve income, employment, services, access and quality of life, not simply the inflation rate. This is a useful preview of broader Economics.
Parent FAQ: Can I tell whether the student is progressing?
Ask them to calculate a new price change, distinguish price level from inflation rate, and explain who could be affected most in two different household scenarios. Progress is visible in those independent answers.
Parent FAQ: Does this prepare students for G3 Economics?
It provides conceptual and numerical groundwork, but G3 Economics K343 is available only at approved schools for school candidates. Families should check their school and follow the correct cohort examination framework.
Parent FAQ: What comes next in Secondary 3?
If the subject is offered and taken, learning becomes more formal: labelled demand–supply diagrams, price elasticity, market failure and structured economic reasoning. The move is from everyday observations to precise models.

The beautiful moment when the lesson works
A student reads a headline: “Inflation falls.” Instead of cheering that everything will be cheaper tomorrow or worrying that the story makes no sense, they ask, “Was the rate lower but still positive? Which index? Compared with which period?” Three small questions replace one large misunderstanding.
That is what careful Secondary 2 Economics learning should feel like in Punggol: a child who can look at changing prices with curiosity, skill and a little more independence, ready to study more complex markets without losing their sense of proportion.
