Ratio, Percentage, Speed —
Mastered Before PSLE Year
P5 is the most difficult year before PSLE. These three topics — ratio, percentage, and speed — account for the majority of marks lost in PSLE Paper 2. Get ahead now.

Why P5 Is the Year Most Parents Wish They Started Sooner
Primary 5 is Singapore math's most demanding year before PSLE. Ratio, percentage, and rate are introduced together — three concepts that all require algebraic thinking skills not yet formally taught. Unlike P4, where topics are harder but still concrete, P5 asks students to reason about relationships between quantities, something that requires a different level of mathematical maturity.
PSLE is just one year away. P5 Semester 1 and Semester 2 results directly predict PSLE readiness. The time to fill gaps is P5 — not P6, when exam practice and revision must take priority and there is no time to rebuild conceptual understanding from scratch.
Model drawing becomes mission-critical in P5. Students who did not develop strong bar model skills in P4 struggle significantly with P5 ratio and fraction-percentage combination problems. Ms Elaine's analysis of 10 years of PSLE Math papers confirms that ratio and percentage together account for the highest proportion of marks in Paper 2.

Signs Your P5 Child Needs Targeted Support
These patterns often appear before assessment results reflect the full picture.
Ratio makes no sense to them
Keeps inverting the ratio or confusing the part with the whole; cannot set up the model correctly.
Percentage change trips them up every time
Finds percentage of a quantity but cannot handle percentage increase, decrease, or reverse percentage.
Speed / Distance / Time — memorised, not understood
Plugs into the formula but selects the wrong variable or cannot rearrange it under pressure.
Model drawing is messy and unhelpful to them
Draws bars but cannot use them to extract the right information; the model and the equation are disconnected.
SA2 results dropped significantly from P4
A clear signal that P5 content has overtaken the child's current level of understanding.
Panics when a problem mixes topics
Can handle ratio alone and percentage alone, but a combined question causes complete shutdown.
How MathArchery Prepares P5 Students for PSLE
Led by Ms Elaine Goh — specialist primary math educator with students from P1 through P6.
Ratio Built From Units, Not Formulas
We teach ratio using the unit method — breaking quantities into equal parts — before introducing any algebraic notation. This gives students a mental model that scales naturally to complex PSLE problems involving multiple ratios and changing quantities.
Percentage With a Single Framework
Whether it is percentage of a quantity, percentage increase, percentage decrease, or reverse percentage, we use one consistent framework. Students do not need to remember which formula applies to which situation.
Speed-Distance-Time as a Triangle
We teach the SDT relationship using a visual reference triangle that students draw automatically when they encounter these problems. This prevents the formula-selection errors that cost marks in Paper 1 MCQ.
PSLE-Style Practice From P5
From mid-P5, students regularly practice PSLE Paper 2 style questions. The problem types, difficulty level, and mark allocation are all representative of what they will face in a year. This removes the shock factor from P6.

What Parents Say
Teacher Elaine is really a diamond amongst tuition teachers. She goes the extra mile to help my daughter when she had difficulty loving math due to her school's math teacher in P5 and teacher Elaine helped her to love the subject so much that she is now asking me to sign her up for year end math to learn more before school lessons. My daughter is now much more confident and does not delay doing her math homework. I am really deeply appreciative of all the hard work and support teacher Elaine has put in to change our lives.
Catherine Chan
We are so grateful to have found Teacher Elaine. She is an incredibly patient and thorough math tutor who has made a huge difference in my son's learning. Her teaching style is clear and methodical, ensuring that my son fully understands each concept before moving on. We can see a significant boost in both his result and confidence. Highly recommend Teacher Elaine to anyone looking for a committed and effective tutor!

Frequently Asked Questions
My child has always been good at math — should I still consider P5 tuition?
P5 is the year that separates good students from exceptional ones. Even students who found P4 manageable often find ratio and percentage unexpectedly difficult. For strong students, MathArchery helps them master P5 content at a depth that positions them for AL1 in PSLE — not just a pass. Tuition at this level is less about catching up and more about building a competitive advantage.
How do you teach ratio — what is your method?
We use the unit method. Every ratio problem is broken down into equal units, which students draw as bar models. Once the units are established, any question — finding one quantity given the other, before-and-after ratio problems, ratios with fractions — follows the same logical process. Students who learn this method in P5 find PSLE Paper 2 ratio problems significantly less daunting.
P5 is a heavy year. How do you avoid burnout?
One 1.5-hour session per week is our standard. We do not encourage excessive tuition — a child who attends five tuition sessions a week is not studying; they are exhausted. Our goal is to make each 1.5-hour session extremely effective through targeted, personalised instruction so your child does not need hours more tuition on top.
My child's P5 SA1 was disappointing. Is it too late to turn around the SA2?
Not at all — P5 SA2 covers the second half of the syllabus, which includes ratio, percentage, and speed. These are also the highest-value topics in PSLE. Strong SA2 performance demonstrates to both student and parent that the fundamentals are in place before the final year. Many families who start after a poor SA1 see significant SA2 improvement within one term.
