Primary 3–4 Mathematics support that helps your child work it out
MOE Primary Mathematics for Primary 3 and 4: whole numbers to 100 000, the four operations, multiplication tables up to 9, fractions and decimals, money, time, length, mass and volume, area and perimeter of squares and rectangles, angles, symmetry and bar graphs.
8 tracked MOE/SEAB skills, from numbers to 100 000 to angles, symmetry and graphs. The tutor asks focused questions, your child tests the next step, and the understanding stays theirs.
Beta subject: Primary 3–4 Mathematics uses a domain-specific Socratic rubric and is currently marked Beta while we benchmark its scaffolding across full Primary 3–4 papers.
What a primary 3–4 mathematics tutor covers
Each skill is tracked separately so strong chapters never mask a shaky prerequisite.
- 1
Numbers to 100 000
Foundation skillRead, write, compare and order numbers up to 100 000, use place value, and round to the nearest 10, 100 or 1000.
- 2
Adding and subtracting
Builds on Numbers to 100 000Add and subtract numbers up to four digits, check answers by estimating, and solve two-step word problems with bar models.
- 3
Multiplying and dividing
Builds on Adding and subtractingRecall the 6, 7, 8 and 9 times tables, multiply and divide a 4-digit number by a 1-digit number, and explain remainders in word problems.
- 4
Fractions and decimals
Builds on Multiplying and dividingFind equivalent fractions, change between mixed numbers and improper fractions, add and subtract like and related fractions, and read decimals to 3 places.
Write amounts in dollars and cents, add and subtract money, and work out the total cost and the change in shopping problems.
Tell time on the 24-hour clock, convert hours, minutes and seconds, and find how long something takes or when it starts or ends.
- 7
Measuring, area and perimeter
Builds on Multiplying and dividingMeasure and convert length, mass and volume in m, cm, kg, g, ℓ and ml, and find the area and perimeter of squares and rectangles.
- 8
Angles, symmetry and graphs
Builds on Numbers to 100 000Name and measure angles, spot right angles, perpendicular and parallel lines, complete symmetric figures, and read bar graphs and tables.
How a primary 3–4 mathematics session unfolds
The student starts by asking for the answer—and ends up solving the key step themselves.
- Student
A ribbon is 8 m long. Siti cuts it into pieces of 30 cm. How many pieces can she cut, and how much ribbon is left?
- Tutor
Let’s make the units match first. The ribbon is in metres and the pieces are in centimetres. How many centimetres are there in 8 m?
- Student
1 m is 100 cm, so 8 m is 800 cm.
- Tutor
Good. Now each piece is 30 cm. Which operation tells you how many 30s fit into 800?
- Student
Division! 800 ÷ 30 is 26 remainder 20, so she cuts 26 pieces and 20 cm is left.
- Tutor
You explained the remainder as well as the answer. Check it: what do 26 pieces of 30 cm and the 20 cm left add up to?
About this illustrative example
This walkthrough is an illustrative script written to show how the five-level hint progression works in Primary 3–4 Mathematics, not a transcript from a real student account.

How skill progress is recorded
Sessions build a clear skill record for the student and a calm, read-only summary for linked parents.
One bar per skill
Mastery is tracked skill by skill, not as a single subject percentage, so a strong topic cannot hide a weak one.
The hint level counts
Getting something right with one small hint moves the bar more than getting it right after five. The number we show you reflects how much help you needed.
Built from an event log
Every attempt, hint and explanation is recorded as an event, and the bars are calculated from that history. It can be replayed, which means the numbers are reproducible rather than asserted.
A parent sees the same numbers
A linked parent gets the same skill bars, the last judgement and its line of evidence behind each level, the recent session summaries and the flag counts — read-only, and nothing that is not also on your own pages.
8 skill bars, tracked independently
In primary 3–4 mathematics, that means 8 separate skill bars — numbers to 100 000, adding and subtracting, multiplying and dividing, and the rest — each updating based on verified problem steps. Linked parents see the same topic bars and session takeaways in read-only mode.
Primary 3–4 Mathematics FAQs
Common questions from parents about this subject on tutor.ai.
How is this different from PSLE Mathematics?
It follows the Primary 3 and 4 part of the MOE syllabus only, with smaller numbers and everyday contexts. Ratio, percentage and speed are left for PSLE Mathematics in Primary 5–6.
Which Primary 3–4 topics are covered?
Aligned to the MOE Primary 3 and 4 Mathematics syllabus. Eight skills, in syllabus order: Numbers to 100 000; Adding and subtracting; Multiplying and dividing; Fractions and decimals; Money; Time; Measuring, area and perimeter; and Angles, symmetry and graphs.
Can my child answer by talking or tapping instead of typing?
Yes. Primary 3–4 students get the Play interface: they can speak to the tutor or tap an answer choice, and each session is planned around ten minutes.
Will it just tell my child the answer?
No. It asks one small question at a time, such as which part of the bar is missing or which unit to change first, so your child does each step.
