Primary 5 in 2027: Maths and Science Syllabus, Exams and PSLE Run-Up

Primary 5 is where the PSLE syllabus really starts. In 2027 a P5 child meets percentage, rate, triangles, volume and five new Science topics, may take some subjects at Foundation level for the first time, and has no mid-year exam, only WAs and an end-of-year paper. Everything learnt this year is tested in the PSLE in 2028.

This guide puts the year in one place: the full P5 topic lists for Maths and Science from MOE's own syllabuses, what changes in English and Mother Tongue, how the Foundation and Standard choice works, what school assessments look like, the 2027 term dates, where children usually get stuck, and a dated plan from now to PSLE 2028.

Who is in Primary 5 in 2027?

The 2021 Maths syllabus has applied to P5 since 2025 and to P6 since 2026, so every child in this guide learns P5 and P6 Maths from the same document. The 2023 Science syllabus started with the 2023 P3 cohort and reached P5 in 2025. Sources: MOE 2021 Primary Mathematics syllabus, updated October 2025 (PDF) and MOE 2023 Primary Science syllabus, updated January 2026 (PDF).

One more change touches this cohort. MOE says the Gifted Education Programme in its current form stops taking new P4 students from 2027, and existing classes continue until the last batch finishes P6 in 2028. That last batch is the P5 class of 2027. See our GEP replacement guide for what replaces it.

P5 Maths syllabus (Standard)

MOE organises primary Maths into three strands: Number and Algebra, Measurement and Geometry, and Statistics. This is the complete P5 Standard list from the 2021 syllabus, in MOE's order.

The P5 Standard list has no Statistics topic. Graphs return in P6 as average.

What is new in P5 Maths compared with P4

Two practical changes come with the content. First, P5 is the first level where the syllabus marks certain skills as "without calculator", which tells you a calculator is now used for other work. At the PSLE, Paper 1 bans calculators and Paper 2 allows them (SEAB PSLE Mathematics 0008 (PDF)). Second, word problems get longer, with more steps per question.

What comes next, in P6

So you can see the whole run to the PSLE, these are the P6 Standard topics in the same syllabus: dividing fractions, percentage (finding the whole, percentage increase and decrease), ratio, algebra, area and circumference of a circle and composite figures with semicircles and quarter circles, volume (finding a missing edge or height), angles in composite figures with special quadrilaterals, and average. Our PSLE Mathematics page covers the exam paper itself.

P5 Foundation Maths

The P5 Foundation Maths syllabus goes back over important P1 to P4 ideas and adds a smaller set of new skills, all of which also appear in Standard Maths. MOE describes the new Foundation content as a subset of Standard Maths.

Percentage, area of a triangle and the volume of a cuboid come later in Foundation, in P6. Source: the same MOE syllabus, pages 45 to 48.

P5 Science syllabus

The 2023 syllabus is built on five themes: Diversity, Cycles, Systems, Interactions and Energy. In P5, every topic sits under Cycles or Systems.

MOE also says what is not required, which saves a lot of over-study: the terms self-pollination and cross-pollination, pollen tubes, foetal development, alveoli, heart chambers and valves, xylem and phloem, stomata, artery, vein and capillary, and transpiration pull.

What is new in P5 Science compared with P4

The jump is less about the number of topics and more about the kind of question. P5 papers ask children to explain processes and to read experiments: what was changed, what was kept the same and what the result shows. The syllabus lists these as practices, for example investigating what affects the rate of evaporation and how bulbs in series or parallel affect a circuit.

Foundation Science in P5

Foundation Science covers the same five P5 topics, with some learning outcomes left out. MOE underlines those outcomes in the syllabus. In Foundation P6, the forces topic covers friction and gravity only. At the PSLE, Foundation Science is a 1 hour 15 minute paper of 70 marks with three-option multiple-choice questions, against 1 hour 45 minutes and 100 marks for Standard Science (SEAB 0039 (PDF) and SEAB 0009 (PDF)).

English and Mother Tongue in P5

English. P5 English follows MOE's 2020 English Language syllabus, which started with the 2020 P1 cohort. It is not a topic list but six areas built up each year: listening and viewing, reading and viewing, speaking and representing, writing and representing, grammar, and vocabulary. In P5 the texts get longer and the writing more demanding. The PSLE English paper now has Situational Writing (14 marks) and Continuous Writing (36 marks, at least 150 words, from three pictures) in Paper 1, then comprehension and language use, listening, and an oral with Reading Aloud and Stimulus-based Conversation. Our PSLE English composition guide and open-ended comprehension guide go deeper.

Mother Tongue. MOE has new 2024 primary syllabuses for Chinese, Malay and Tamil, but they start with the 2024 P1 cohort. A child in P5 in 2027 stays on the 2015 Mother Tongue syllabus. At the end of P4, a child who passes all four subjects and does very well in Mother Tongue may be offered Higher Mother Tongue from P5. Foundation Mother Tongue is also possible. For Chinese, the PSLE has a composition (40 marks), a language and comprehension paper (90 marks), an oral of reading aloud and a video-based conversation (50 marks) and listening (20 marks). See our PSLE Chinese composition guide and Higher Chinese guide.

Foundation or Standard: how the choice works

Subject-based banding lets a child take a mix of Standard and Foundation subjects in P5 and P6. MOE describes it in three steps.

Source: MOE, subject-based banding for primary school, updated 5 December 2025.

How it counts at the PSLE. A Standard subject is graded AL1 to AL8. A Foundation subject is graded A, B or C, and these count as AL6, AL7 and AL8 in the PSLE Score. A Foundation grade A also lets a child take that subject at G2 in secondary school. Our PSLE AL scores guide has the full mark bands.

How to decide. Ask the subject teacher two questions: is the gap in understanding, or in exam speed and carelessness, and what would Foundation change about daily lessons? If the gap is understanding of P3 and P4 work, Foundation gives time to rebuild it. If it is speed or carelessness, Standard with targeted practice usually makes more sense. Remember the end-of-P5 review: a P5 choice can be adjusted.

How P5 assessments work

There is no mid-year exam in P5. MOE removed the mid-year exam for P3, P5, Sec 1 and Sec 3 between 2019 and 2021, and asked schools to report marks as whole numbers without class or level positions (MOE, 28 September 2018). What most primary schools use instead, described generally:

Each school sets its own number of WAs and the weight of each, so the assessment plan your school shares early in Term 1 is the one that counts. In Science, MOE recommends that 15% to 30% of school-based assessment is performance-based, such as practical work, with 70% to 85% from written tests. Our WA1, WA2 and SA2 guide explains the terms and the weightings schools use.

The P5 EOY is the result that matters most this year, because it feeds the end-of-P5 review of subject levels.

2027 term dates for Primary 5

MOE published the 2027 calendar on 14 July 2026. These dates are final.

School holidays in term: Tuesday 9 February (Chinese New Year in lieu), Monday 3 May (Labour Day in lieu), Monday 5 July (after Youth Day), Tuesday 10 August (day after National Day), Friday 3 September (Teachers' Day) and Friday 8 October (Children's Day, primary schools only). Public holidays in term include Hari Raya Puasa on 10 March, Good Friday on 26 March, Hari Raya Haji on 17 May, Vesak Day on 20 May, National Day on 9 August and Deepavali on 28 October.

Where P5 children usually get stuck

Maths

• Fractions of a fraction. Multiplying fractions is new, and so is reading "two-fifths of the remainder". Children who are shaky on equivalent fractions from P3 and P4 fall behind quickly here.
• Percentage of what. The hard part is not the sum but the base. "20% of the total" and "20% of what is left" give different answers, and many marks are lost on that one word.
• Rate. Children find the unit rate but forget to scale it back up, or mix up which quantity is "per".
• Triangles. The height must be perpendicular to the base. In an obtuse triangle it often falls outside the shape, which catches many children.
• Volume and tanks. Questions mix cm³ and litres. The key fact from the syllabus is that 1 litre is 1000 cm³.
• Angle reasoning. Each step needs a reason (angles on a straight line, isosceles triangle). Children who see the answer but cannot write the steps lose method marks.

Ratio worries usually belong to P6 under the current syllabus. The fraction and percentage habits built in P5 are what make P6 ratio manageable, as our three linked topics guide and heuristics guide explain.

Science

• Open-ended answers. In the PSLE Standard paper, Booklet B has 10 to 11 structured questions worth 2 to 5 marks each, 40 marks in all. Children who know the content still lose marks by writing one vague line.
• Experiments. Saying which variable was changed, which were kept the same and what the result shows is a skill on its own, and P5 is where it starts to count.
• Exact words. "Water vapour" is not "steam" or "water". "Gains heat" is not "gets hot". Our keyword trap guide covers the common slips.
• Circuits. Series and parallel arrangements, and why a circuit is open or closed.

Worked examples with real numbers

Fractions (P5 Standard). 2¾ − 1⅚. Change both to twelfths: 33/12 − 22/12 = 11/12.

Percentage, discount and GST. A bag costs $80. It has a 15% discount, and 9% GST is added to the discounted price. Discount = 15% of $80 = $12, so the price is $68. GST = 9% of $68 = $6.12. The bag costs $74.12. (GST in Singapore has been 9% since 1 January 2024, per IRAS/basics-of-gst/current-gst-rates). PSLE questions state the rate they want.)

Annual interest. $2000 is saved for one year at 2% interest a year. Interest = 2% of $2000 = $40, so the amount at the end of the year is $2040.

Rate. A tap fills 12 litres in 3 minutes. The rate is 12 ÷ 3 = 4 litres per minute. A 30-litre tank takes 30 ÷ 4 = 7.5 minutes.

Area of a triangle. Base 10 cm, height 6 cm. Area = ½ × 10 × 6 = 30 cm².

Volume of water in a tank. A tank is 40 cm long and 25 cm wide, and the water is 18 cm deep. Volume = 40 × 25 × 18 = 18 000 cm³, which is 18 litres.

Angles. An isosceles triangle has one angle of 40° between its two equal sides. The other two angles are equal, so each is (180° − 40°) ÷ 2 = 70°.

Science open-ended answer. Question: Mum hung two identical wet towels outside on the same afternoon, one in a sheltered corner and one on a windy balcony. The towel on the balcony dried first. Explain why.

The stronger answer names the factor (wind), the process (evaporation) and links them to the result. That is the habit to build all year.

How parents can help, week to week

Use what the school gives you. The Student Learning Space (SLS) is MOE's online platform with curriculum-aligned resources for every student in national schools, and the school's own worksheets are written to the current syllabus.

Keep it in proportion. P5 is a hard year, but it is not the PSLE. A disappointing WA is information, not a verdict.

When to consider tuition, honestly

Many children get through P5 without tuition. It is worth considering when:

• the same topic keeps going wrong after you and the teacher have both tried to help
• P3 or P4 gaps, especially fractions, are blocking new work
• your child understands lessons but cannot explain answers in Science or show working in Maths
• the end-of-P4 recommendation put a subject at Foundation and you want to rebuild before the end-of-P5 review.

It is probably not needed if your child is coping, marks are steady and the main issue is the normal jump in difficulty. In that case, consistent practice at home and the school's resources are usually enough. If you do look, ask a tutor which syllabus year they teach from, because P5 topic lists changed in 2025. Our guides on whether tuition is necessary and when to start set out the trade-offs. When you are ready, see our Primary 5 tuition, P5 Maths tuition and P5 Science tuition pages.

From P5 to PSLE 2028: the timeline

2027 dates come from MOE's published calendar. 2028 dates are not published yet, so they are expected windows, each set beside the 2026 date.

What if P5 goes wrong

• A poor WA1. It is one small part of the year. Find the two topics that cost the most marks and redo them before WA2.
• The EOY is far below the WAs. EOY papers cover the whole year in a longer format. Check whether marks went on content or on time, then plan the P6 holidays around the answer.
• The school recommends moving a subject to Foundation at the end of P5. Ask what evidence it is based on and what Foundation would change in P6. A Foundation grade A still counts as AL6 and opens G2 in secondary school.
• Your child wants to move back to Standard. Raise it with the teacher early in P5, not after the EOY, so there is time to show the school your child can cope.
• Your child is anxious. Talk to the form teacher or the school counsellor. For urgent help, national mindline 1771 is open 24 hours (MOH, mental health services).
