Many parents first meet the psle maths paper format when their child comes home in Primary 5 or 6 talking about “Paper 1, no calculator” and “Paper 2, calculator allowed”. The split matters more than it sounds. The two papers test different skills, feel very different to sit, and need slightly different preparation. This guide explains how the Primary School Leaving Examination (PSLE) Mathematics paper is structured, how the calculator rules work, and what that means for practice at home.
A quick note before we start: the PSLE is run by the Singapore Examinations and Assessment Board (SEAB) with the Ministry of Education (MOE). Formats are reviewed from time to time, so always check the current syllabus and exam format documents on the SEAB website, and the information your child’s school sends home, for the year your child sits the exam.

How the PSLE Maths Exam Is Structured
PSLE Mathematics is taken as two written papers, usually sat on the same day with a short break in between.
- Paper 1 is done without a calculator. It focuses on number sense, mental and written calculation, and short questions. In recent years it has been split into two booklets: one with multiple-choice questions and one with short-answer questions where only the final answer is written.
- Paper 2 allows an approved calculator. It has short-answer questions plus longer structured problem-sum questions, where working must be shown and method marks are awarded.
In recent years, Paper 1 has been about one hour and Paper 2 about one and a half hours, but durations, number of questions and mark allocations can change, so confirm them in SEAB’s current format document rather than relying on older practice papers.
Students taking Foundation Mathematics (a subject level offered from Primary 5 for students who need more support) also sit a two-paper exam with a similar calculator split, but with content and question demands set at the foundation level. The school will tell you which level your child is taking.
Paper 1 vs Paper 2 at a Glance
| Feature | Paper 1 | Paper 2 |
|---|---|---|
| Calculator | Not allowed | Approved calculator allowed |
| Main question types | Multiple choice and short answers | Short answers and longer structured problems |
| Working shown | Usually only the final answer is marked | Working is important, method marks are given |
| Skills stressed | Number sense, mental sums, fractions, quick recall | Multi-step reasoning, heuristics, careful setting out |
| Common pitfall | Careless arithmetic under time pressure | Skipping steps or misreading what is asked |
When Calculators Are Allowed, and the Rules Around Them
The simple rule is: no calculator for Paper 1, calculator allowed for Paper 2. In practice, the paper is handed out in a way that makes this clear, and invigilators will tell candidates when calculators may be used.
A few points parents often ask about:
- Approved models only. Calculators used in national exams must meet SEAB’s rules. SEAB publishes guidance on approved calculators. The SEAB-approved calculators guide on our site covers O-Level and A-Level lists, which are separate; for the PSLE, check what your child’s school recommends and SEAB’s current PSLE instructions. Many schools tell Primary 5 pupils which model to buy so everyone practises on the same type.
- No programmable or communication features. Calculators that store text, connect wirelessly or do symbolic algebra are not permitted. Covers and instruction leaflets are often required to be removed.
- Check the battery early. A calculator that dies mid-paper is the candidate’s problem. Test it the week before and make sure it is a model your child has used all year.
- Calculator use is still a skill. Children who rely on the calculator for simple steps lose time and can key in errors. Encourage estimating the answer first so a wrong key press stands out.
Preparing for Paper 1 (No Calculator)
Paper 1 rewards fluency. Questions are short, but there are many of them, and small arithmetic slips cost marks because usually only the final answer is checked.
Ideas that help:
- Daily short drills on times tables, fractions, decimals and percentage conversions. Ten minutes a day beats one long weekend session.
- Mental strategies such as splitting numbers (for example, 25 × 16 as 25 × 4 × 4) and spotting friendly numbers.
- Checking habits. Teach your child to reread the question, check units, and ask “does this answer make sense?”
- Pacing. In timed practice, if a question is taking too long, mark it and come back. Multiple-choice questions should not be left blank.
Preparing for Paper 2 (Calculator Allowed)
Paper 2 is where the well-known problem sums live. The calculator removes heavy arithmetic, but it does not help with understanding the problem.
- Read, draw, then calculate. Model drawing, tables and listing are common heuristics taught in Singapore primary schools. Encourage your child to sketch before reaching for the calculator.
- Show working clearly. Method marks can rescue a question even if the final answer is wrong. Neat, step-by-step lines with labels (“Cost of 1 pen = …”) help markers follow the logic.
- Answer the actual question. Many marks are lost by finding the right quantity for the wrong person or leaving out the final step.
- Practise on the real calculator, including fractions and remainders, so there are no surprises on the day.
Exam Day Tips for Parents
- Pack the approved calculator, pencils, eraser, ruler, protractor and a set square if required by the school’s list, plus a water bottle.
- Keep the morning calm. A familiar breakfast and leaving on time matter more than last-minute revision.
- Remind your child that a hard question is hard for everyone. Moving on and returning later is a sensible strategy, not giving up.
- After the paper, avoid a question-by-question post-mortem. There is another subject to prepare for, and the result will not change.
If something goes wrong on exam day, such as illness, read what happens if your child misses a national exam paper and contact the school immediately.

Supporting Your Child Without Adding Pressure
Maths anxiety is common in the final year of primary school. Praise effort and good habits, not just scores. If your child seems unusually stressed, withdrawn or unable to sleep, speak to their form teacher or the school counsellor early. Knowing exactly how the two papers work, and practising each in the right way, often takes a lot of the fear out of the exam.
