If your child could handle Primary 6 Maths but now freezes when they see a page full of x’s, I’d start by asking them to talk me through one question. Can they tell me what the letter stands for? Can they explain why the minus sign is there? Their answers usually give me a better starting point than the mark at the top of the page.
At Jimmy Tuition, I help Secondary 1 students get comfortable with the move from PSLE Maths to lower secondary Maths. In-person group classes are held in Woodlands, near Admiralty MRT, and capped at six students per class so I can see how each student works through a question.

What we work on in Secondary 1 Maths
Bring a recent worksheet, quiz or Weighted Assessment if you have one. I can use it to see what your child already understands, where the working goes off track and what to practise first. The order of topics can differ by school and subject level, so tell me what your child is covering this term.
- Numbers and operations. Make sense of negative numbers, fractions and the order of operations. Practise checking whether an answer is reasonable before moving on.
- Algebra and linear equations. Translate words into expressions, simplify like terms, expand brackets and solve equations one line at a time.
- Ratio, percentages, rate and speed. Identify what the numbers refer to, choose the right units and show enough working to explain the answer.
- Geometry and data. Label diagrams clearly, explain angle relationships and read graphs and tables carefully.
For an overview of how topics vary by subject level, see the MOE G2 and G3 Mathematics syllabuses.
Five common Sec 1 Maths mistakes and how to fix them
1. Losing a sign when subtracting a negative
For −3 − (−5), I ask, “Which way would you move on the number line?” Subtracting negative five means moving five places to the right. Write the intermediate step −3 + 5 = 2 until the signs feel familiar.
2. Combining terms that don’t belong together
3x + 2 doesn’t become 5x. Think of it as three bags with x items in each, plus two loose items. You can combine 3x + 2x = 5x because all five bags contain the same number.
3. Multiplying only the first term in a bracket
In −2(x − 3), the −2 multiplies both terms. Write (−2)(x) + (−2)(−3) = −2x + 6. The second product is the one I ask students to check before carrying on.
4. Solving an equation without keeping it balanced
For 3x − 4 = 11, add 4 to both sides to get 3x = 15, then divide both sides by 3. Put x = 5 back into the original equation. If 3(5) − 4 = 11, you have a quick check you can do on your own.
5. Using the wrong amount as the percentage base
If a price rises from $40 to $50, the increase is $10. The question is how big that increase is compared with the original price, so calculate 10 ÷ 40 × 100% = 25%. Underline the starting amount before reaching for the calculator.
How we use mistakes to prepare for school assessments
Once we’ve corrected a question together, I like to give the student a similar one with different numbers. I’ll ask them to explain what they changed in their working. If they can do the second question and explain why the method works, they’re more likely to recognise it when the next school paper phrases it differently.
At home, try asking your child, “Which line would you check first?” That small question can tell you whether they’re unsure about the topic or just need a habit for catching sign and unit errors.
