A Parents’ Guide to: What is G2 Math for Secondary School?

Parents have been hearing a lot about G1, G2 and G3 ever since Full Subject-Based Banding (Full SBB) replaced the old “Express / Normal (Academic) / Normal (Technical)” streams. But what does G2 Math actually mean for your child? Is it a “lower” Math? Can they still move up? Will it affect subject combinations in Sec 3? And should you send your child for tuition if they are already taking G2?

This guide explains G2 Math in plain language, using official MOE and SEAB sources, and connects it to what we already teach in Punggol at eduKatePunggol.com and edukatesingapore.com. It’s written for parents who want to support their Sec 1–4 child in 2026 and beyond.

You can read the official MOE page on Full SBB here: https://www.moe.gov.sg/microsites/psle-fsbb/full-subject-based-banding/secondary-school-experience.html. (moe.gov.sg)

1. First Things First: What Does “G2” Mean?

“G” stands for General. Under Full SBB, every secondary student learns subjects at G1, G2 or G3:

G3 ≈ the old Express standard
G2 ≈ the old Normal (Academic) standard
G1 ≈ the old Normal (Technical) standard

This mapping is stated clearly on MOE’s Full SBB pages and summarised in many school guides. (kiasuparents.com)

So, G2 Math is not “random” or “school-made” Math — it is the nationally published Mathematics syllabus mapped from the former N(A) Math, updated and renamed for Full SBB. You can actually see the official document here:

MOE “Curriculum for secondary schools” page — scroll to 2020 G2 and G3 Mathematics Syllabuses: https://www.moe.gov.sg/secondary/schools-offering-full-sbb/syllabus. (moe.gov.sg)

That means: if your child is taking G2 Math, they are still following an MOE/SEAB syllabus, still assessed in school, and still building toward national exams. It is not a “dead-end” subject.

2. Who Usually Takes G2 Math?

Most Sec 1 students who entered secondary school with a Posting Group 2 score are offered their core subjects — English, Math, Science, MTL — at G2 first. Some students from Posting Group 3 but who offered Foundation Math at PSLE may also start at G2 for better pacing. This is stated on MOE’s 2025–2026 curriculum page: “For students who offered English, Mathematics or Science at Foundation level at PSLE … they may choose to take these subjects at a less demanding level (i.e. G2).” (moe.gov.sg)

Schools can later allow students to take that subject at a more demanding level, i.e. from G2 → G3, if they show strong results in Sec 1 or Sec 2. MOE’s Full SBB explanation here shows the mechanism: https://www.moe.gov.sg/microsites/psle-fsbb/full-subject-based-banding/about-full-sbb.html. (moe.gov.sg)

So G2 is best thought of like this:

G2 Math = Standard national Math for students who need a steadier pace, but who can still move up to G3 later.

3. What Is Actually Inside G2 Math?

If you open the MOE/SEAB Mathematics files, you will see that G2 Math still has the classic three strands:

Number and Algebra
Geometry and Measurement
Statistics and Probability
This matches the old NA / Express structure. (moe.gov.sg)

Typical Lower Secondary G2 topics include:

Integers, factors, multiples
Algebraic expressions and simple equations
Linear graphs
Percentages and ratio (revisited from primary, but at secondary depth)
Perimeter, area, volume, Pythagoras’ theorem
Basic data handling and statistical diagrams
(Compare with outline here: https://home-tuition.sg/academic-syllabus/moe-secondary-1-and-2-math-syllabus/) (Schooltopia – Home Tuition Singapore)

At Upper Secondary G2, the content lines up with what used to be N(A)-Level Mathematics: more algebraic manipulation, formulae for plane geometry, coordinate geometry, basic trigonometry, and more applied data tasks. Parents can see the original 2020 “Express/NA Maths Syllabuses” PDF here (still the backbone in 2025–2026): https://www.moe.gov.sg/-/media/files/secondary/syllabuses/maths/2020-express_na-maths_syllabuses.pdf. (moe.gov.sg)

So if your child is on G2 Math, they are still covering real algebra, real geometry, real problem solving — just with more guided progression and less sudden jumps than in G3.

4. How Is G2 Math Different from G3 Math?

Difficulty & Depth. G3 goes faster and deeper — more non-routine algebra, more abstract geometry, and earlier prep for O-Level 4052 Mathematics. G2 keeps the same ideas but with smaller steps and more real-life contexts. MOE says G1/G2/G3 are “mapped from N(T), N(A) and Express standards respectively.” (moe.gov.sg)

Pace. G3 students may finish topics earlier in the year so they can start exam-type papers sooner. G2 students stay longer on core skills — fractions/ratio review, linear graphs, formulae for area/volume — so they don’t get lost.

Assessment. School-based assessment for G2 may contain more structured questions and fewer very-high-order items, but it still tests understanding, explanation and accuracy. If your child later progresses to G3, they will meet the more demanding question types.

Outcome. A student doing well in G2 Math can:

be moved to G3 Math for Sec 2 or Sec 3,
take G3 Math but G2 for another subject,
or keep G2 and still qualify for ITE/Poly pathways that accept G2-level Maths passes. This is why MOE describes Full SBB as keeping pathways open. (moe.gov.sg)

Area / Aspect	G2 Math (≈ former N(A) standard)	G3 Math (≈ former Express standard)
MOE Level	“Moderately demanding” level under Full SBB (G2)	“Most demanding” level under Full SBB (G3)
Typical Entry	Students from Posting Group 2, or students who took Foundation Math at PSLE and need steadier pacing	Students from Posting Group 3, or G2 students who have shown strong results and can be stretched
Learning Pace	Slower, more time on core skills, more guided practice	Faster, assumes strong P6 foundation, moves to problem-solving earlier
Main Focus	Secure number skills, algebra basics, linear graphs, geometry formulas, applied/statistical tasks	Master full lower-sec algebra, wider variety of non-routine questions, earlier exam-style work
Algebra Depth	Simple algebraic expressions, equations, basic expansion/factorisation	Full expansion/factorisation, simultaneous equations, harder manipulation
Geometry & Measurement	Pythagoras, basic constructions, standard mensuration	All G2 topics plus more abstract/combined geometry and coordinate geometry
Graphs & Functions	Linear graphs, simple interpretation	Linear + sometimes quadratic/variation-type tasks depending on school
Statistics & Data	Read/interpret tables, charts, basic averages, real-life context	All G2 tasks plus more demanding interpretation/comparison questions
Problem-Solving Demand	More structured questions, clearer scaffolds, fewer “big jump” items	More unstructured questions, multi-step reasoning, algebra inside context problems
Classroom Expectation	Teacher guidance, step-by-step worked examples, time to copy correct working	Student independence, ability to explain method, attempt extension/homework without full steps
Assessment Style	School papers with higher proportion of short/structured response, fewer very-high-order items	School papers with bigger Section B / long questions, marks for method and explanation
Common Student Profile	“Can do the work, but needs time / gets stuck when question wording changes”	“Can transfer method to a new problem and finish on time”
Progression Option	Can promote G2 → G3 if results and teachers support it	Baseline for taking A-Math and for stronger Sec 3 subject combinations
Impact on A-Math	Needs upgrade to G3 first (or clear evidence of strength) before most schools will offer A-Math	Natural pathway to A-Math in Sec 3–4
What Tuition Should Do	Re-teach P6 gaps, align to MOE topic order, drill reading of questions, start preview of G3 topics	Keep up with school pace, train speed & accuracy, expose to exams, push for distinction
Parent’s Key Question	“How do I make sure G2 doesn’t become a ceiling?”	“How do I maintain G3 standard and get into A-Math / stronger Sec 3 combo?”
Good Local Fit	3-pax, near Punggol MRT, weekly corrections, topic-by-topic mastery	3-pax, near Punggol MRT, graded homework, timed practices, full-paper drills

5. Can My Child Move from G2 Math to G3 Math?

Yes — and this is one reason many parents choose tuition in Sec 1–2.

MOE states clearly: students “will have the flexibility to adjust their subject levels at appropriate junctures, based on their strengths, interests and learning needs.” (MOE: Secondary school experience under Full SBB) (moe.gov.sg)

In practice, schools look for:

Strong school test results in G2 Math
Consistent homework / classwork
Teacher recommendation
Willingness to cope with heavier load (since G3 links to A-Math in upper sec)

This is where a centre like eduKatePunggol.com comes in — we already run G2 and G3 Math side by side in 3-pax groups, so if a student stabilises at G2, we can preview G3 algebra or G3 graphing with them. See our dedicated page here: Punggol Secondary 1 Mathematics Tutor — Full SBB G2/G3 3 Pax. (edukatesingapore.com)

6. Why Schools and MOE Created G2 Math

Before Full SBB, an N(A) student who was strong in Math had two problems:

They were stuck in a stream even if they could do Express-level Math.
If they jumped to a harder paper, it felt “too far” and they lost confidence.

Full SBB and G2 Math remove both problems. G2 provides a recognised, national level of Math that:

is not as heavy as G3,
but is not as practical-only as G1,
and can be stepped up when the student is ready.

This is described in parent-friendly terms here:

7. What G2 Math Looks Like in a Punggol Tuition Centre

At eduKate Punggol, our secondary Math pages already teach from the same MOE file you saw above. You can see it here:

What we do with G2 students:

Re-teach P6 → Sec 1 basics (fractions, percentages, ratio, units) because many G2 students’ mistakes come from primary gaps.
Teach each MOE topic in the exact school order (you can check this on your child’s school LMS and on MOE’s syllabus page). (moe.gov.sg)
Run G2-style worksheets — more structured parts, less “jump” than G3, but still with reasoning.
Preview G3 items for students aiming to move up.
Use 3-pax small groups near Punggol MRT so we can watch each student’s working and correct misconceptions fast. (Location is here: https://edukatepunggol.com/) (edukatepunggol.com)

This makes it possible for a Sec 1 G2 student to become a Sec 2 G3 student — something parents often ask about.

8. Will G2 Math Affect Post-Secondary Pathways?

Not necessarily — it depends on the full mix of subject levels. MOE’s pages make it clear that students “will subsequently access programmes and post-secondary pathways based on their various subjects and subject level combinations.” (MOE, 12 Jun 2025) (moe.gov.sg)

That means:

A child with mostly G3 but G2 Math can still go on to many polytechnic courses.
A child with mostly G2 but very strong G2 Math + Science can still qualify for good N(A)/Polyroutes.
A child who later moves G2 → G3 Math will have a stronger case for A-Math or more demanding Sec 3 combinations.

This is also what local schools explain in their Full SBB FAQ documents, e.g. OPSS FSBB FAQ (2025): https://www.orchidparksec.moe.edu.sg/files/FSBB%20FAQs.pdf. (orchidparksec.moe.edu.sg)

So, G2 Math does not “close doors” — it tells the school your child is taking Math at a level that is right for them right now.

9. How Parents Can Support a Child in G2 Math

Check the actual MOE topic list. Sit with your child and open the syllabus: https://www.moe.gov.sg/secondary/schools-offering-full-sbb/syllabus. Ask, “Which of these are you doing in school now?” This shows your child that G2 is official, not “lesser”. (moe.gov.sg)
Match tuition to that list. Send your child to a centre that teaches from MOE/SEAB, not random worksheets. Our Punggol centre does exactly that: https://edukatesingapore.com/secondary-1-math-tuition-punggol-how-to-understand-sec-1-math/. (edukatesingapore.com)
Watch for signs of readiness to move up. If school tests are high (A/B range) and your child is finishing work fast, talk to the school about G3.
Keep English strong. Many G2 Math mistakes happen because students misread the question — so our Punggol English page is useful too: https://edukatesingapore.com/secondary-english-tuition-punggol-how-to-understand-sec-english-with-edukatesingapore-com/. (edukatesingapore.com)
Stay close to attendance. Because G2 is designed to build confidence step by step, missing just 2–3 weeks can cause a big gap.

10. FAQs Parents Ask About G2 Math

Q1: Is G2 Math “harder than primary”?
Yes. Even at G2, secondary Math moves to algebra, graphs and geometry that are not in primary. The difference is that G2 gives more time and scaffolding. See the bridge from primary to secondary here: https://www.moe.gov.sg/-/media/files/primary/2021-primary-mathematics-syllabus-p1-to-p6-updated-dec-2024.pdf. Primary was redesigned precisely to prepare for this. (moe.gov.sg)

Q2: Can my child take A-Math if they started with G2 Math?
Yes — if they later move up to G3 and cope well in lower secondary. Schools will look at Sec 1–2 results before allowing A-Math. This is why early intervention in Punggol is helpful, e.g. https://edukatesingapore.com/punggol-full-sbb-g3-mathematics-tutor-3-pax-small-groups-a1-tuition/. (edukatesingapore.com)

Q3: What if my child can’t cope even with G2 Math?
Then G1 is available — still official, still MOE — and some schools will recommend it to protect the child’s confidence. But before dropping, many parents try targeted 3-pax tuition first.

Q4: Will taking G2 Math make my child “less than” classmates?
No. Full SBB was created to remove that idea. Students sit together in mixed form classes; they are only separated for subject-level lessons. MOE explains this clearly here: https://www.moe.gov.sg/secondary/schools-offering-full-sbb. (moe.gov.sg)

Closing to Parents

G2 Math is not a downgrade — it is MOE’s way of telling schools, “Teach this child at a pace where they can succeed now, and open the door to move up later.” As long as you know what the official G2 syllabus is, match tuition to it, and monitor progress each term, your child can still reach G3, still take A-Math, and still enter strong post-secondary pathways.

If you want this taught in 3-student classes near Punggol MRT, you can contact us at eduKatePunggol.com and we will slot your child into a G2/G3-appropriate group and show you, topic by topic, how we will move them up.
