If your child finds PSLE Math word problems overwhelming, you’re not alone. Many students struggle not because they lack effort, but because PSLE Math demands strong problem-solving skills under time pressure. With complex multi-step questions and high expectations, even diligent learners can feel stuck.

With the right focus and a clear problem-solving framework aligned to the MOE mathematics curriculum,your child can move from frustration to AL1 with confidence.

What are the common PSLE Math Topics?

Based on our review of the last five years of SEAB examination papers, four key topic areas account for nearly 60% of all PSLE Math marks.

By prioritising these areas early, students can revise more effectively on frequently tested topics.

Topics

Priority

Weightage

Action

Fractions, Ratio & Percentage

🔴 CRITICAL

~45%

Master first, appear in almost every Paper 2 question

Whole Numbers & Word Problems

🟡 HIGH

~18%

Foundation for all problem-solving

Geometry (Area/Perimeter)

🟡 HIGH

10–15%

Requires strong visualisation skills

Speed & Algebra

🟢 MEDIUM

8–12%

Tests both formula knowledge and logical reasoning

Percentages are based on observed trends across recent PSLE papers and may vary slightly year to year.

What parents can do:

Have your child complete 2-3 diagnostic papers this week. Identify which of these 4 areas needs the most attention. You can download our Free PSLE Math practice resources here.

The 3-Step Approach to Problem-Solving Questions

Knowing what to study is half the battle. The next step is knowing how to approach each PSLE Math question in a clear and systematic way.

Step 1: Understand

  • Read the question twice without attempting to solve

  • Underline keywords (e.g., “Total,” “Remaining,” “Difference” “At first”)

  • Identify what the question is asking for

Step 2: Apply and Solve

  • Choose the most suitable heuristic for the question

  • Visualise the solution path

  • Show all workings clearly and label diagrams properly to secure method marks

Step 3: Answer

  • Check if your answer makes sense (e.g. A person’s height can’t be 300cm)

  • Are all units correct and labelled?

  • Did you answer what was asked?

Students who apply this framework consistently see noticeable improvements in their problem-solving scores compared with students who rush into calculations. Below, we will use this 3-step approach for the example Math questions.

Master the Heuristics in PSLE Math

Heuristics are systematic problem-solving tools that make complex PSLE Math questions manageable. They are critical in scoring well for PSLE Math.

Some commonly tested heuristics include:

  • Model Drawing
  • Working Backwards
  • Guess and check
  • Assumption Method
  • Using Equations
  • Before-After
  • Make a list/tab
  • Looking for patterns

Model Drawing

When to use: Questions involve fractions, ratio, percentage, or before-after comparisons (appears in 40%+ of Paper 2)

Example: Mrs. Tan bought some apples and oranges. 3/5 of the fruits were apples. After she gave away 24 apples, she had an equal number of apples and oranges left. How many fruits did she buy at first?

Example Solution: Model Drawing

Step 1: Understand the question

  • 3/5 of the fruits were apples
    Apples = 3u
    Orange = 2u

 

Step 2: Apply and Solve

PSLE Math Model Drawing Example

PSLE Math Model Drawing Example

After giving 24 apples away, Apples = Oranges

Since Oranges stayed at 2 units, Apples would also be 2 units

1 unit = 24, so Total fruits at first (5 units) = 24 × 5 = 120 fruits

Step 3: Answer

Mrs. Tan bought 120 fruits at first.

With the model method, students are able to visualise the questions more easily. It is the most powerful tool for PSLE Math problem-solving questions.

Working Backwards

Start from the desired result and work backwards to find the starting point.

When to use: Question gives the end result and asks for the beginning. Keywords include “at first,” “originally,” “in the beginning”

Example:
Giselle and Katrina were playing a card game using 96 picture cards. In the first game, Katrina lost 15 of her cards to Giselle. In the second game, Giselle lost 13 of her cards to Katrina. After the second game, both girls had the same number of picture cards. How many picture cards did Giselle have at first?

Example Solution: Working Backwards

Step 1: Understand the question

  • Total number of cards = 96
  • Since both girls ended with the same number of cards and the total of 96 did not change, they will ended with 48 cards each: 96 / 2 = 48
  • First game: Giselle gained 15 cards
  • Second game: Giselle lost 13 cards

Step 2: Apply & Solve

96 ÷ 2 = 48
Giselle ended with 48 cards.

Second game
Giselle’s no. of cards = 48 + 13 = 61

First game
Giselle’s no. of cards = 61 – 15 = 46

Step 3: Answer

Giselle had 46 picture cards at first.

Guess and Check 

Make an educated guess and check if it meets the problem’s requirements.

When to use: Problems providing two sets of totals; small set of numbers 

Example:
Mrs Lim bought
50 chicken sandwiches and egg sandwiches. Each chicken sandwich cost $2 and each egg sandwich cost $2.80. The total cost of the chicken sandwiches was $13.60 more than the total cost of the egg sandwiches. How many more chicken sandwiches than egg sandwiches did she buy?

Example Solution: Guess and Check

Step 1: Understand the question

  • Data given: Chicken sandwich = $2 ; Egg sandwich = $2.80
  • Total of 50 sandwiches
  • There are more chicken sandwiches ($13.60 more)
  • Create a guess and check table

 

Step 2: Apply and solve

Tip for guess and check: Start with a logical middle value, then adjust systematically.

No. of chicken sandwich Total Cost of chicken sandwich No. of egg sandwich Total cost of egg sandwich Difference in cost (cost of chicken sandwich – cost of egg sandwich) Check
30 30 x $2 = $60 50 – 30 = 20 20 x $2.80 = $ 56 $60 – $56 = $4 X
31 31 x $2 = $62 50 – 31 = 19 19 x $2.80 = $53.20 $62 – $53.20 = $8.8 X
32 32 x $2 = $64 50 – 32 = 18 18 x $2.80 = $50.40 $64 – $50.40 = $13.60  Ok! 

Step 3: Answer

Chicken sandwich – Egg sandwich = 32 – 18 = 14 more chicken sandwich

Assumption Method

(Or suppositions) is a problem solving method used to find two unknowns by making an assumption.

When to use: This method works better when you have a simple total to work with at the end (e.g. total legs, total value of coins, etc.).

Example:
A farmer has chickens and rabbits. There are 35 animals in total with 94 legs altogether. How many chickens and how many rabbits are there?

Example Solution: Assumption Method

Step 1: Understand the question

  • 2 unknowns: Chickens and Rabbits
  • Make an assumption that all animals are chicken
  • Look for the difference in value and solve accordingly

Step 2: Apply & Solve

  1. Make an assumption: Assume all animals are chickens (2 legs each)
  2. Based on the assumption: No. of legs = 35 x 2 = 70 legs
  3. Find the shortage: Actual legs – Assumed legs = 94 – 70 = 24
  4. Find the change in no. of legs when replacing one chicken with rabbit:
    4 – 2 = 2
    Number of rabbits = 24 ÷ 2 = 12 rabbits
    Number of chicken = 35 – 12 = 23 chicken

Step 3: Answer

There are 12 rabbits and 23 chickens.

Verify: (23 x 2) = 46 + (12 x 4) = 94 legs

Other useful heuristics your child will learn:

  • Using equations 
  • Before-after concept 
  • Making systematic lists 
  • Looking for patterns

Time Management: The “1 Minute Per Mark” Rule

Besides understanding the topics, students need to learn to manage their time during the PSLE Math exam. Poor time management causes incomplete PSLE Math papers, one of the top reasons students underperform despite knowing the content. Students commonly get stuck at difficult questions and fail to finish the rest, resulting in lost marks. Based on understanding the SEAB Exam Paper Syllabus, it is important to plan and manage time ahead of the PSLE exam.

 

Paper 1 (Booklet A – 1 hour 10 minutes, 50 marks)

  • MCQ: Maximum 1-2 minutes each
  • Short answer question: Allocate time acoording to marks
  • Don’t get stuck: If you can’t solve an MCQ in 2 minutes, make an educated guess and move on
  • Reserve last 10 minutes for checking

Paper 2 (Booklet B – 1 hour 20 minutes, 50 marks)

  • General Rule: 1 minute per mark (5-mark question = 5-6 minutes maximum)
  • Time allocation:
    1. 55 min: Answer all questions you can do confidently
    2. 15 min: Tackle difficult problems
    3. 10 min: Check for careless mistakes

Common Careless Mistakes:

  • Misreading “difference” as “total”
  • Not answering what was asked (finding speed instead of time)
  • Unit errors (mixing cm and m, hours and minutes)
  • Calculation errors in basic operations
  • Copying numbers wrongly from question to working

10-Minute Checking System

✓ Check for Answers: Did you write all answers in correct spaces with units?
✓ Verify calculations: Make sure there are no calculation errors
✓ Common sense: Do answers make logical sense?
✓ Question requirements: Did you answer what was actually asked?
✓ High-mark questions: Double-check all 4-5 mark questions

When Self-Study Isn’t Enough

Consider additional support if your child:

  • Practices regularly but shows little improvement
  • Shows math anxiety affecting exam performance
  • Has weak P4-P5 fundamentals
  • Understands concepts but struggles with application

Early intervention, ideally 6+ months before PSLE, is most effective. Small gaps become major obstacles if left unaddressed.
