PSLE Mathematics Common Mistakes: How to Avoid Them

PSLE Mathematics mistakes often cost students 5-10 marks unnecessarily. Many of these mistakes are preventable with awareness and practice. Here are the most common mistakes our tutors see, and how to avoid them.

Mistake 1: Misreading the Question

Students rush through questions and miss critical details like "nearest 10", "to 2 decimal places", or "in metres". Always read the question twice before answering. Underline the key requirements.

Mistake 2: Careless Arithmetic Errors

Simple calculation mistakes (e.g., 7 × 8 = 54 instead of 56) cost easy marks. Always double-check arithmetic, especially in multi-step problems. Use a calculator if allowed.

Mistake 3: Not Showing Working

PSLE awards method marks for correct working even if the final answer is wrong. Always show every step clearly. Write each calculation on a new line.

Mistake 4: Incorrect Unit Conversion

Students forget to convert units (e.g., metres to centimetres, hours to minutes). Always check the units in the question and convert if necessary.

Mistake 5: Wrong Interpretation of Word Problems

Word problems require careful reading. Identify what is given, what is asked, and which operations are needed. Draw a diagram if helpful.
