Singapore primary maths, level by level

A parent's overview of P1 to P6

If you've ever looked at your child's maths book and wondered what they're actually meant to know this year, this is the short version — one section per level, in plain English.

This is a parent-friendly summary of the topics we practise at each level, written to follow the Singapore MOE primary syllabus as closely as we can. It is not an official MOE document, and your child's school sets the order they teach things in. Check their actual workbook if you need the exact sequence.

Primary 1

Age 6–7 · learning that numbers are made of other numbers

Number bondsAdding within 20 Taking awayCounting & comparing Ordinal numbersShapes Telling timeMoney Word problems

The year's real job is fluency with small numbers, and the idea that a whole splits into parts (number bonds). Everything later leans on this. If your child still counts on fingers for 7 + 3, that's the thing worth practising — not the next topic.

Primary 2

Age 7–8 · bigger numbers, and the start of multiplication

Add within 1000Subtract within 1000 Times tables 2, 3, 4, 5, 10Sharing (division) Halves & quartersWord problems

Regrouping ("carrying" and "borrowing") arrives here and trips up a lot of children — usually because place value isn't solid, not because they can't add. Multiplication starts as groups of, which is why 3 × 4 and 4 × 3 are taught as different pictures of the same answer.

Primary 3

Age 8–9 · the year the jump gets noticeable

Times tables to 9Division with remainder Numbers to 10 000Adding fractions PerimeterWord problems

Many parents notice the difficulty step here. Two-step word problems appear, remainders stop being tidy, and fractions begin properly. Weak times tables hurt most in P3 — division, fractions and later ratio all sit on top of them.

Primary 4

Age 9–10 · decimals and precision

RoundingFactors & multiples DecimalsMixed numbers Area of a rectangleWord problems

Decimals and fractions are now two views of the same thing, and children are expected to move between them. Money problems become decimal problems. Careless place-value slips cost more marks than genuine misunderstanding at this level.

Primary 5

Age 10–11 · the PSLE groundwork year

Order of operationsFraction of a number PercentageRatio AverageVolume of a cuboid Word problems

Percentage, ratio and fractions are really one idea wearing three hats, and children who see that cope far better than those memorising three separate methods. Multi-step problems become the norm rather than the exception.

Primary 6

Age 11–12 · putting it all together

AlgebraFraction operations Percentage changeCircles Ratio & proportionAverage Word problems

Little is genuinely new — most of P6 is combining earlier topics inside longer problems, plus a first taste of algebra. Discount and increase questions are just percentage with a story attached. Practising reading the problem matters as much as the arithmetic by now.

One thing that is not on the list

Speed — distance, time and speed — is deliberately absent. MOE removed it from the primary syllabus, so we don't practise it either. If you're using an older assessment book, you may still find it in there.

Where children actually lose marks

In our experience building this, it's rarely the arithmetic. It's the words. A child who can calculate 40 × 3 instantly can still be stuck on "one packet holds 40 sweets, Ali buys 3 packets" — because the hard part is turning the sentence into a sum. That's why there are word problems at every level, not just the upper ones.
