Free, distraction-free math drills aligned to the MOE syllabus. No sign-up needed to try.
Ask most families how they revise math before PSLE and you'll hear some version of: "We do a bit of everything. Work through the textbook exercises. Do some assessment book pages." It feels thorough. It's actually quite inefficient.
Here's the problem: "a bit of everything" spends equal time on topics your child has already mastered and topics where they have real gaps. If your child has fractions under control but struggles with percentage word problems, a general revision session might spend 30 minutes confirming they already know fractions — and 10 minutes glancing at percentages before moving on.
With limited time before major assessments, the gap between targeted practice and general revision matters a lot. The Skill Map on Singapore Math Drills exists to make targeted practice possible — and specific enough to actually move the needle.
The Singapore MOE Primary Mathematics syllabus covers a large amount of ground: number and algebra, measurement and geometry, statistics, and across six year levels, more than 60 distinct topic units. No child has equal mastery across all of them.
What most children actually have is a specific mastery pattern: strong in some areas, weak in others, with the weaknesses often concentrated in a few subtopics rather than spread evenly. A child who struggles with fractions might actually be perfectly fine with comparing and ordering fractions — their gap is specifically in fraction of a set or mixed number operations.
The distinction matters because different subtopics require different practice. "Do more fractions" is not a useful instruction. "Do more mixed number operations, specifically adding mixed numbers with unlike denominators" is.
Without a tool that tracks at subtopic level, it's hard to know the difference. The Skill Map gives you that visibility.
The Skill Map is the topic-by-topic progress tracker on every student's dashboard. It groups the curriculum into visual progress rings — one per major topic unit — and shows mastery level at a glance using a four-tier system:
Tapping any unit ring opens a detailed view showing not just the overall mastery, but the nested subtopics within that unit. So "Fractions" might show Mastered for "Comparing and Ordering Fractions" and Struggling for "Dividing Fractions." The gap is visible at the level where it actually matters.
Once you've identified a specific subtopic that needs work, the Skill Map lets you launch a targeted drill session on that subtopic alone — not the whole topic, not "fractions in general," but dividing fractions specifically.
This is meaningfully different from a standard drill session, which draws from the full topic breadth. A targeted drill session concentrates all questions on the identified gap. If your child has 20 minutes before dinner, a targeted session on one struggling subtopic will do more for their mastery than a general session that visits everything briefly.
Scenario: A P5 student is preparing for the end-of-year exam. Their Skill Map shows:
| Subtopic | Status |
|---|---|
| Adding/Subtracting Fractions | Mastered |
| Mixed Numbers | Proficient |
| Multiplying Fractions | Proficient |
| Dividing Fractions | Struggling |
| Fraction Word Problems | Developing |
Two clear priorities emerge: Dividing Fractions (the worst gap) and Fraction Word Problems (a gap likely connected to the dividing gap, since many fraction word problems require division).
The recommendation: this week, run three targeted sessions on Dividing Fractions before touching Fraction Word Problems. Once Dividing Fractions moves to Developing, Fraction Word Problems will likely improve naturally because the underlying operation is more secure.
Without the Skill Map, this student would have been doing "fraction revision" — which might have spent significant time on Adding/Subtracting Fractions (already Mastered) and relatively little time on the actual gap.
If a subtopic drops below 60% accuracy, it is automatically surfaced as a Focus Area — a flag that both the student's dashboard and the parent's weekly digest highlight. Focus Areas come with prerequisite suggestions: if dividing fractions is flagged, the system might note that multiplying fractions is the prerequisite operation, and check whether that's also shaky.
This matters because the root cause of a gap isn't always the gap itself. A child who struggles with fraction word problems might actually have a gap in reading comprehension of mathematical language — they understand dividing fractions mechanically but can't identify when to apply it in a word problem context. The prerequisite chain surfaces these dependencies so you're addressing root causes, not symptoms.
A practical approach for families in the months before PSLE:
Week 1: map the landscape. Look at the Skill Map together and make a list of every subtopic at Struggling or Developing. Don't try to fix everything at once — just get the full picture.
Weeks 2–6: targeted sessions, one gap at a time. Pick the highest-priority Struggling subtopic (usually the one that blocks the most downstream content) and run targeted sessions on it until it reaches at least Developing. Then move to the next.
Weekly check-ins: Look at Focus Areas in the weekly digest every Sunday. If a previously Proficient subtopic has slipped back to Developing, add a session of targeted practice to catch it before the regression deepens.
Two weeks before the exam: switch to Worksheet Mode. Once the most significant gaps are addressed, shift to Worksheet Mode for integrated practice across all topics — simulating the exam condition of facing diverse question types without topic scaffolding.
The Skill Map is individual — each child has their own map. If you're on Family Pro (up to 2 children) or Family Max (up to 4 children), you can view each child's Skill Map separately from the parent dashboard and see which subtopics each child needs to target that week.
Two siblings in different year levels will have completely different patterns of gaps and mastery — which is exactly why a one-size-fits-all revision plan rarely works for families. The Skill Map makes it practical to support each child's specific needs without needing to diagnose the gaps yourself.
The Skill Map populates from the first session — even the free placement quiz gives you an initial read. Start a free trial, complete a few practice sessions, and within a week you'll have enough data to run your first targeted drill session on a real gap.
