Singapore Math is a mathematics teaching methodology developed by Singapore's Ministry of Education that emphasizes deep conceptual understanding through the Concrete-Pictorial-Abstract (CPA) approach, bar modeling for problem-solving, and mastery of fewer concepts at greater depth.
What is Singapore Math?
Singapore Math refers to the mathematics curriculum and teaching approach developed in Singapore during the 1980s that has since become one of the most popular homeschool math options worldwide. The methodology is famous for producing students who consistently rank #1 in international math assessments (PISA, TIMSS). Rather than emphasizing rote memorization and speed, Singapore Math builds deep conceptual understanding through visual representations, mental math strategies, and systematic problem-solving techniques that prepare students for advanced mathematics.
Key Takeaways
- Based on the CPA approach: Concrete (manipulatives) to Pictorial (diagrams) to Abstract (numbers)
- Bar modeling technique helps students visualize and solve complex word problems
- Curriculum covers K-8; considered about one year ahead of typical U.S. programs
- Main curriculum options: Primary Mathematics and Dimensions Math from Singapore Math Inc.
- Requires parent preparation; not designed for independent study in elementary years
The CPA Approach
The foundation of Singapore Math is the Concrete-Pictorial-Abstract (CPA) framework based on psychologist Jerome Bruner's research. Students first manipulate physical objects (base-ten blocks, counters, fraction tiles) to understand concepts hands-on. Then they draw visual representations (bar models, number bonds, diagrams) to bridge toward abstract thinking. Finally, they work with numbers and mathematical symbols. Singapore's Ministry of Education won't approve teaching materials that skip this progression. The CPA approach ensures students understand why math works, not just how to perform procedures.
Bar Modeling
Bar modeling is Singapore Math's signature problem-solving technique. Students draw rectangular bars to represent known and unknown quantities in word problems. This visual approach helps students determine what information is given, what needs to be found, and how quantities relate to each other. Bar modeling bridges arithmetic and algebra; students solving problems with bars are essentially doing algebra without formal algebraic notation. The technique applies across topics including fractions, ratios, percentages, and multi-step word problems that would otherwise require algebraic equations.

Tips for Success
Singapore Math works brilliantly but requires parent investment, especially initially. Always take the free placement test since Singapore runs about a year ahead of U.S. programs and covers concepts in different sequences. Use the Home Instructor's Guide, which walks you through concepts and provides teaching scripts. Don't skip the concrete phase even if your child seems ready for abstract work; the visual foundation pays dividends later. Expect the first month to feel challenging as you learn the methodology. Consider the 2022 Edition if you're finding Primary Mathematics difficult to teach, as it's more scripted and parent-friendly.
The Bottom Line
Singapore Math's track record speaks for itself: Singapore students consistently top international mathematics rankings. The curriculum builds genuine mathematical understanding rather than surface-level procedural knowledge. The investment is parent preparation and involvement, particularly in elementary years. For families willing to learn the methodology and work alongside their children, Singapore Math provides an exceptionally strong mathematical foundation that prepares students for advanced coursework.
