Did you know? Foundation Maths and G1 Maths are different courses at different stages of school. Foundation Mathematics is a primary-school subject leading to PSLE. G1 Mathematics is a secondary-school subject level leading to the relevant SEC examination. Shared building blocks do not make their syllabuses, papers or subject codes interchangeable.
Keep three labels separate: your child’s primary Maths course, the Posting Group used for Secondary 1 admission, and the Maths subject level confirmed by the secondary school. PG1, PG2 and PG3 concern posting and help guide initial subject levels; G1, G2 and G3 describe subject levels. The word “Foundation” on a primary book does not by itself tell you the child’s whole secondary subject combination.
Before buying resources, ask the school to confirm the Maths level and current teaching topics. Then check the official document for the right stage, subject and examination year. SEAB lists Foundation Mathematics as 0038 for 2026 PSLE and G1 Mathematics as K110 for 2027 SEC school candidates. The chapters below show how to connect the stages, choose useful practice and discuss progress without treating a label as a permanent limit.

The quickest way to clear up the confusion is to read the cover carefully. “Foundation Mathematics” belongs to the primary-school context. “G1 Mathematics” belongs to the secondary-school context. A book’s marketing description may use “foundation” to mean basic practice as well, so check the actual course and level rather than relying on that word alone.
| Label | Stage and purpose | What to verify |
|---|---|---|
| Foundation Mathematics | Primary course and PSLE subject | School’s confirmed primary course and PSLE year |
| PG1, PG2 or PG3 | Secondary admission grouping | Official posting information |
| G1, G2 or G3 Mathematics | Secondary subject level | School’s confirmed Maths level and current syllabus |
| SEC Mathematics code | Examination subject identification | Level, candidate category and examination year |
A P6 worksheet can still reveal a useful prerequisite for secondary learning. It does not become a complete G1 resource because a student finds it helpful. Equally, an unfamiliar secondary question is not evidence that every primary skill has been lost.
For the wider progression, see how Maths progresses from P1 to SEC. This article focuses on the particular naming confusion at the primary-to-secondary transition.
Avoid predicting a student’s full secondary arrangement from one primary subject label. MOE explains that Posting Groups are used for secondary posting and to guide initial subject levels. Read the child’s actual results and posting information together with the school’s confirmed subject arrangements.
The question “Which Posting Group?” and the question “Which level of Maths?” are related, but they are not identical. Under Full Subject-Based Banding, subject levels can differ across a student’s subjects. MOE’s secondary school experience explanation is the policy reference for these arrangements.
If you are asking about eligibility for a particular initial level, use the current official criteria for that subject and intake. Ask the receiving school to explain how they apply to your child. This guide does not infer eligibility from the Foundation label or provide a shortcut score conversion.
Write down the confirmed subject combination. A clear record of Maths, English, Mother Tongue and Science levels is more useful for choosing books than a general description of the child as “a PG1 student”. For the wider admission decision, use the existing post-PSLE choices guide.
SEAB’s 2026 PSLE formats page lists Foundation Mathematics as 0038. Its 2027 SEC G1 school-candidate catalogue lists Mathematics as K110. These are dated examples of different subjects at different stages, not instructions to use the same documents for every later cohort.
Match five details before choosing an examination resource: stage, subject, subject level, examination year and candidate category. For a student starting secondary school in 2027, the 2027 SEC catalogue is not automatically their eventual examination-year specification. Recheck when the relevant document is available.
For current lessons, start with the school’s booklist and taught topics. An eventual SEC syllabus is useful for understanding the destination, but it is not a week-by-week Secondary 1 lesson plan. If two schools introduce topics in a different sequence, that alone does not mean one has missed the curriculum.
Use the topic-order guide to organise revision around what has been taught. For examination-resource checks, the existing revision resource and syllabus audit provides the broader method.
A useful primary book may support a named gap. Label its purpose clearly: “practice interpreting fractions”, for example. That prevents a support resource from quietly becoming the assumed secondary syllabus.
Did you know? A short explanation can show more about a learning gap than a long page of correct answers. Start with the secondary teacher’s current topic and identify the earlier skill it relies on. Choose a small check, observe the attempt and ask the teacher whether it matches the support needed.
| Illustrative check | What to listen for | Possible next practice |
|---|---|---|
| Find one quarter of 20 counters | Four equal groups; five in each | Represent the fraction with objects or a drawing |
| Add $2.40 and $1.75 | Place value and dollars/cents | Write aligned amounts and check the total |
| Explain a worked solution | Why each step follows from the question | Annotate one step before attempting a similar problem |
| Read a short word problem | What is known and what is being asked | Restate the question before calculating |
In the money example, the total is $4.15. If the child writes $3.115, ask them to represent the amounts before showing a corrected method. You are looking for the point where the meaning becomes uncertain, not only for a corrected final answer.
Record any help supplied. Reading the problem aloud, identifying an operation and demonstrating a calculation are different interventions. A correct answer after a demonstration is a useful learning moment, but it is not yet evidence that the skill can be used independently.
Keep practice connected to the school’s next step. The Secondary 1 readiness guide covers the wider transition, including routines and confirmed subject arrangements.
MOE’s Full SBB explanation allows for subject-level adjustments at appropriate points based on students’ strengths, interests and learning needs. A change is a school-guided decision, not an automatic reward for finishing a workbook or attending tuition. Discuss the current arrangement and review process with the school.
Ask four practical questions: “Which skill needs attention now?”, “What evidence would show readiness for the next step?”, “What support is available?”, and “When is a suitable review point?” Ask about the demands of the proposed level and the student’s wider workload as well.
An illustrative home observation might be: “He can now explain the calculation in a similar question without prompting, but still needs help interpreting the longer instruction.” Share both parts. This gives the teacher a clearer picture than saying the child has become “good at Maths”.
Keep the conversation encouraging and precise. The primary Foundation course is part of the child’s learning history. The current secondary level tells you what to teach and practise now. Progress is best discussed through the work the child can do and the support they need next.
For the whole pathway, return to the MOE and SEAB syllabus finder. For teaching questions about the secondary Maths transition, the Clementi Secondary 1 Maths reference provides the established eduKate context; confirm suitability and current arrangements when enquiring.
