What's covered
Curriculum alignment
Mathematics Syllabus, Primary One to Six (MOE, 2021 syllabus)
Taught across P1–P6.
Olibits is an independent learning platform and is not affiliated with or endorsed by the Ministry of Education. See our FAQ for the full breakdown.
Where students commonly get stuck
- Mixing up part-whole and comparison models in word problems, especially once two or more unknowns are involved.
- Fraction operations (adding, subtracting, converting) once denominators stop matching.
- Long division and multi-step arithmetic under time pressure, where a single slip changes the final answer.
Parent tip
When your child gets a word problem wrong, ask them to draw or describe the model before re-solving it. Most mistakes come from misreading the relationship between numbers, not from the arithmetic itself.
Real Math practice questions
Pulled directly from the live Olibits question bank: the same questions a child would actually see, not separately written for this page.
P1 · Ordinal Numbers & Position
What is the ordinal number for position 5?
5th ✓
5st
5rd
five-th
Position 5 is written as '5th'.
P2 · Length, Mass & Volume
Which is heavier: a bag of 500 g of sugar or a bag of 1 kg of flour?
The 1 kg bag of flour ✓
The 500 g bag of sugar
They weigh the same
Cannot tell
1 kg = 1000 g, which is heavier than 500 g.
P3 · Numbers to 10,000
What is the value of the thousands digit in 2748?
2000 ✓
700
48
3000
In 2748, the digit 2 is in the thousands place, so its value is 2000.
P4 · Fractions
Convert 2 3/4 into an improper fraction.
11/4 ✓
9/4
11/8
10/4
Multiply the whole number by the denominator and add the numerator: 2 × 4 + 3 = 11, keeping the denominator 4. So 2 3/4 = 11/4.
P5 · Whole Numbers
A teacher wants to split 81 pencils into equal groups of 9. Is this possible with no pencils left over?
Yes ✓
No
81 ÷ 9 = 9 exactly, with no remainder, so 9 is a factor of 81.
P6 · Ratio
Express the ratio 15 : 20 in its simplest form.
4:3
15:20
3:5
3:4 ✓
Divide both parts by their highest common factor, 5: 15 ÷ 5 : 20 ÷ 5 = 3:4.
