Mastering Heuristic Math Questions in PSLE with the Unit Table Method
One of the biggest challenges in PSLE Math is solving heuristic questions effectively. Many students struggle with these non-routine problems that require logical reasoning and problem-solving skills beyond simple arithmetic. At Daniel’s Math Tuition, we don’t just teach formulas—we equip students with structured problem-solving techniques like the Unit Table Method to help them confidently tackle complex questions step by step.
What Are Heuristic Questions in PSLE Math?
Heuristic questions test students’ ability to analyze, reason, and apply mathematical concepts in unfamiliar scenarios. These problems often appear in Paper 2 of the PSLE Math Exam, requiring students to go beyond rote memorization and think critically. If your child has ever stared at a math problem, unsure where to begin, they were likely dealing with a heuristic question.
Common heuristic strategies include:
- Guess & Check
- Working Backwards
- Assumption Method
- Before & After Concept
- Unit Transfer Method
- Systematic Listing
One of the most effective techniques for solving ratio-based heuristic questions is the Unit Table Method.
What is the Unit Table Method?
The Unit Table Method is a structured way to organize information when dealing with problems involving proportional reasoning, changes in quantities, and transfer of units. Instead of randomly plugging numbers, students use this method to break down problems systematically and minimize mistakes.
Why Use the Unit Table?
✅ Helps organize complex information in a clear, structured manner
✅ Reduces errors by aligning all given values systematically
✅ Saves time in the exam by making calculations more efficient
✅ Works well for problems involving ratios, before-and-after scenarios, and transfers
How to Apply the Unit Table in PSLE Heuristic Questions
Step 1: Identify the Variables
Before constructing the unit table, identify the key quantities in the problem. These could be objects, people, or values that change.
Step 2: Construct the Table
Organize the information in a table format, ensuring that each row represents a different scenario (e.g., before vs. after, two different groups, or changes over time).
Step 3: Assign Units and Relationships
Use basic unit ratios to determine the relationships between different variables. If the problem involves transfers, update the table accordingly.
Step 4: Solve Step by Step
Once the table is complete, use logical reasoning and algebraic steps to arrive at the final answer.
Example of the Unit Table in Action
Question:
A farmer has some chickens and cows. The total number of legs among them is 72. If there are twice as many chickens as cows, how many chickens does the farmer have?
Using the Unit Table Method:
| Number of Chickens | Number of Cows | Total Legs | |
|---|---|---|---|
| Step 1: Assign Units | 2u | u | (2u × 2) + (u × 4) = 72 |
| Step 2: Solve for the unit | 4u + 4u = 72 | u = 9 | |
| Step 3: Find Chickens | 2 × 9 = 18 |
Final Answer: The farmer has 18 chickens.
Making Heuristic Questions Manageable
PSLE heuristic questions can feel intimidating, but mastering structured methods like the Unit Table makes them much more approachable. Many of our students have gone from feeling overwhelmed by these problems to solving them confidently and efficiently.
