P5 Math Assessment Books 2026: A Parent's Honest Review

TLDR: FAN Math's bundle (S$57.10) is best for struggling students needing step‑by‑step scaffolding. Casco's Primary Five Mathematics Tutor (S$15.90–22.80 per volume) suits average students who need extensive practice. OnSponge Essential Problem Solving Skills (S$16.90) is ideal for advanced students ready for heuristic‑heavy questions. Singapore students complete only 60% of assessment books on average (KiasuParents, 2024) — buy one book your child will actually finish, not a shelf of untouched titles.

The Reality of Assessment Book Fatigue

Assessment books are a S$1.8 billion industry in Singapore, yet most collect dust after the first few chapters. According to a KiasuParents survey of 120 Singapore parents (2024), primary students complete only 60% of their assessment books on average, with some finishing as little as 10–15%. This waste stems from buying books that don't match the child's current ability or learning style. With the average P5 Math assessment book costing S$15–25, choosing the right one is both an educational and financial decision.

This review compares the four most‑recommended P5 Math assessment series, evaluated against three criteria aligned with the MOE 2021 Mathematics Syllabus: clarity of explanations, progression design, and syllabus alignment. Each book was assessed for its suitability at different Achievement Level (AL) bands, from struggling (AL5–AL6) to advanced (AL1–AL2) learners.

In‑Depth Reviews

1. FAN Math P5 Bundle — The Systematic Rebuilder

FAN Math's three‑book system is designed for students who need to rebuild their Math foundation from the ground up. The bundle includes Teach‑n‑Learn (topic‑by‑topic concept introduction), Process Skills in Problem Solving (heuristic training covering 8 methods including draw‑a‑diagram, work‑backwards, and make‑a‑list), and Simulated Mathematics Exam Papers (full‑length timed practice with OAS answer sheets).

Best for: Students who scored AL4–AL5 in P4 and need to rebuild confidence before tackling P5's more abstract topics (fractions, ratios, percentages). The bundle's sequential design ensures no gaps in understanding, which is critical because MOE data shows that P5 is where 40% of students experience their first significant drop in Math grades.

Pros:

• Scaffolded learning: Each topic begins with a "Let's Learn" section that models thinking aloud — a technique that NIE research (2024) shows improves concept retention by 28% compared to direct practice.
• Heuristic focus: Book 2 explicitly teaches 8 problem‑solving heuristics aligned with the MOE 2021 syllabus framework.
• Exam‑ready: Book 3's papers mimic school SA2 and PSLE format, including OAS shading practice.

Cons:

• Price: At S$57.10, it's the most expensive option — roughly 2–3× the cost of a single Casco volume.
• Volume: Three books can intimidate an already‑stressed child. Recommend starting with Book 1 only and adding Books 2–3 only after 70% completion.

Verdict: Worth the investment if your child's Math foundation is shaky. Use Book 1 over June holidays, Book 2 in Term 3, Book 3 in Term 4. FAN Math's structured approach mirrors the "mastery before progression" principle that Singapore's own pedagogy is built on (MOE, 2021).

2. Casco Primary Five Mathematics Tutor — The Practice Powerhouse

Casco's Mathematics Tutor series has been a staple in Singapore households for over 15 years. Two volumes cover the full P5 syllabus: Volume 5A addresses Whole Numbers, Fractions, and Area of Triangles; Volume 5B covers Ratio, Percentage, Volume, and Geometry. Each volume contains 200+ questions with fully worked solutions.

Best for: Students consistently scoring AL3–AL4 who need repetitive, varied practice to achieve mastery. Research from NIE (2023) found that students who complete 150+ practice questions per topic score an average of 12% higher on school assessments — Casco's question volume supports this threshold.

Pros:

• Comprehensive coverage: Leaves no topic untouched — even niche subtopics like "Volume of Composite Solids" get dedicated sections that other books often skip.
• Worked examples: Every new question type is preceded by a detailed solution showing both the "what" and the "why", which helps parents who struggle to explain Math to their children.
• Affordability: Each volume is priced competitively at S$15.90–22.80, making it one of the most cost‑effective options per practice question.

Cons:

• Dense layout: Small fonts, cramped spacing — can be visually overwhelming for some children. Parents report that younger or easily‑distracted students may find the pages intimidating.
• Limited heuristic variety: Mostly reinforces standard bar‑model and unitary methods; less emphasis on alternative approaches like guess‑and‑check or making a table.

Verdict: The go‑to for "drill and practice" families. Buy one volume at a time to avoid overwhelming your child. At roughly S$0.08 per question, it offers the best value for practice‑focused learners.

3. OnSponge Essential Problem Solving Skills — The Heuristic Trainer

OnSponge takes a fundamentally different approach: instead of covering every topic exhaustively, it focuses on problem‑solving heuristics for P5 topics (Whole Numbers, Fractions, Rate, Geometry, Area of Triangle, Percentage, Volume). Each chapter includes "Let's Get Started" foundational questions, scaffolded practice, and review questions that ramp up to PSLE‑challenge level.

Best for: Students scoring AL1–AL2 who already understand concepts but need to sharpen their ability to tackle non‑routine, multi‑step problems — the exact question type that separates AL1 from AL2 on the PSLE, according to SEAB's mark‑differentiation framework.

Pros:

• Multiple solution methods: Shows 2–3 ways to solve the same problem, encouraging flexible thinking. Research from the University of Singapore (2025) found that students exposed to multiple solution methods scored 19% higher on non‑routine problems.
• Scaffolded difficulty: Questions within each topic progress from basic to PSLE‑challenge level, so the book grows with the student.
• Clean, spacious layout: Ample writing space and clear diagrams reduce cognitive load — particularly important for the complex multi‑step problems P5 students face.

Cons:

• Assumes prior knowledge: Minimal concept explanation — not suitable for struggling students who need foundational reteaching before tackling problem sums.
• Narrow focus: Only covers problem sums; no MCQ or short‑answer practice, which make up roughly 40% of the PSLE Math paper.

Verdict: Ideal for advanced students preparing for GEP screening or aiming for PSLE Math AL1. Pair with a topical MCQ book like Casco for full‑spectrum revision. OnSponge's heuristic‑first approach mirrors the MOE's emphasis on "thinking skills over rote calculation" (MOE Mathematics Syllabus, 2021).

4. SAP Learning Maths 5 — The Visual Learner's Choice

SAP's Learning Maths series distinguishes itself through visual design. Colour‑coded chapters with "Watch Out!" sidebars highlight common mistakes, "Hint" boxes provide visual prompts, and "Quick Check" mini‑quizzes appear after each subtopic to reinforce learning.

Best for: Students who are visual learners or easily discouraged by dense text. According to NIE's 2024 learning‑styles study, approximately 65% of primary school students show a preference for visual‑spatial learning aids, making SAP's colour‑coded approach broadly appealing.

Pros:

• Visual scaffolding: Diagrams and colour coding help children "see" the math — particularly effective for abstract P5 topics like fractions and ratios.
• Mistake‑focused learning: "Watch Out!" sidebars pre‑empt errors before they happen, reducing the frustration cycle that demotivates many students.
• Bite‑sized sections: Short, manageable segments prevent fatigue — each section can typically be completed in 15–20 minutes, matching the attention span research recommends for P5 learners.

Cons:

• Fewer practice questions: About 60–80 questions per topic vs. Casco's 200+, which may not provide enough repetition for mastery.
• Less challenging: Top‑end questions rarely reach PSLE‑challenge level, so advanced students may outgrow the book by mid‑year.

Verdict: A gentle entry point for students who find Math intimidating. Supplement with past‑year papers later in the year to bridge the difficulty gap. SAP's visual approach is particularly effective for the first half of P5, when students are adjusting to the jump in abstraction.

How to Choose — A Step‑by‑Step Guide for Parents

Choosing the right assessment book starts with understanding where your child currently stands. Follow these steps to match the book to your child's ability level and learning style, based on MOE's AL banding system.

Step 1: Check your child's latest school report. Their most recent Math grade is the strongest predictor of which book will work best.
→ AL5/AL6: Start with FAN Math Book 1 (Teach‑n‑Learn) only.
→ AL3/AL4: Pick Casco Volume 5A.
→ AL1/AL2: Go straight to OnSponge.

Step 2: Visit Popular Bookstore together. Let your child flip through 2–3 shortlisted books before buying. A 2025 NIE study found that children who chose their own assessment books completed 23% more of the book than those whose parents chose for them. Which layout feels less intimidating? Buy that one.

Step 3: Set a completion goal. Aim for 70% of the book by SA2. If progress stalls after 4 weeks, switch to a different series — don't force a mismatch. The KiasuParents survey (2024) found that forced completion correlates with lower Math scores, not higher.

Step 4: Pair with digital practice. Use SgStudyPal's adaptive quizzes to identify weak topics, then target those sections in the assessment book. A blended approach (print + digital) yielded 15% higher scores in NIE's 2025 study of 500 P5 students.

The One‑Book‑Only Rule

Singaporean households own an average of 8.3 assessment books per primary‑school child (KiasuParents, 2024), yet completion rates remain stubbornly low. Research from NIE (2023) shows that deep practice with one well‑chosen book yields better results than skimming multiple books — students who focused on a single book scored 14% higher on average than those who spread effort across 3+ books.

Our recommendation: Buy one book from the above list that matches your child's current ability — not the ability you hope they'll have by PSLE. Commit to finishing at least 70% of it before considering another. This focused approach reduces clutter, lowers stress, and actually improves grades. As MOE's own Mathematics Syllabus (2021) emphasises, "depth of understanding is more important than breadth of practice."
