Dimensions or Primary? (PDF)

The Dimensions Math program is a cohesive PK-8 series (Primary Mathematics is Grades 1-6). It is an updated version of the Singapore math approach that includes much more material to support educators.

Grades PK-K include specific visualization activities and provide suggestions for small group and center work. Lessons in Grades 1-5 are well-defined and follow a consistent sequence. They begin with a problem for discussion, move to an explanation of the concepts, introduce vocabulary, and provide various approaches to solving the problem. This is followed by a set of learning tasks that extend the concept, ending with a set of problems to assess understanding. 

Textbooks and Workbooks include additional problems. Workbook exercises are differentiated and include basic problems, practice problems, and challenging problems.

Teacher’s Guides are in full color and include reduced-size copies of the textbook and workbook pages for easy reference to every lesson. The Teacher’s Guides give more ideas for differentiation and include math literature suggestions.

In typical U.S. math programs, students get a worked example, then solve problems that very closely follow that example, repeating all the same steps with different numbers. In Singapore math, students must think through concepts and apply them in new ways from the very start. Since they can’t rely on simple replication, students are pushed to greater engagement and broader thinking. In U.S. math programs, concepts and skills are more compartmentalized within and across grade levels than in Singapore math, where a strong sense of connectivity to past learning is woven throughout.

View the Dimensions Math® PK–5 series overview (PDF). Dimensions Math is designed to better serve U.S. teachers and students. We’ve updated aspects of Singapore math curriculum for clarity and relevance, while preserving the solid foundation that makes it unique. The series follows the principles outlined in the Singapore mathematics framework, including the Concrete, Pictorial, Abstract (CPA) approach, mental math strategies, and bar modeling.

In the Dimensions Math program, concepts are introduced and explained in a new format with vibrant imagery, while the progression and scope that define Singapore math remain intact.

Dimensions Math Program

Yes. Textbooks contain learning tasks that are central to lessons, as well as practices and reviews to be done in class. Workbooks contain additional practice and independent work, which can be assigned as homework or completed in the classroom.

The first year of use, the cost is $48 per student including all necessary Textbooks and Workbooks. In the second year and beyond, the cost is $24 per student (because Textbooks are reusable). This does not include Teacher’s Guides or Tests.

Each lesson opens with a problem to encourage student curiosity and introduce new concepts. Lessons include discussion and exploration, strategic use of manipulatives, and exercises that progress systematically. 

Workbooks offer independent practice while maintaining the careful progression of exercise variation. They are where students hone their skills, and are a necessary component of the series.

Dimensions or Primary (PDF)

Dimensions Math 1–5 follows the same Singapore math approach as Primary Mathematics 1–6. It emphasizes the CPA (Concrete, Pictorial, Abstract) progression. It centers on the use of number bonds and bar models to solve word problems, and encourages the mastery of mental math to gain number sense, computational fluency, and logical thinking.

The problem solving processes of the learning tasks deepen and broaden student understanding of concepts (in contrast to the method of simply following an example to solve a similar problem). There is minimal vocabulary and textual information. Concepts are conveyed primarily through images and careful sequencing.

Dimensions Math PK–5 is not precisely aligned with the Common Core State Standards, but covers the standards in its own unique progression. The few standards not included in the Textbooks (for example, line plots of measurements to fractions of an inch in Grade 3) are covered in the Teacher’s Guides.

In the Dimensions Math program, concepts are introduced and explained in a new format with vibrant imagery, while the progression and scope that define Singapore math remain intact.

Singapore Math Method

In typical U.S. math programs, students get a worked example, then solve problems that very closely follow that example, repeating all the same steps with different numbers. In Singapore math, students must think through concepts and apply them in new ways from the very start. Since they can’t rely on simple replication, students are pushed to greater engagement and broader thinking. In U.S. math programs, concepts and skills are more compartmentalized within and across grade levels than in Singapore math, where a strong sense of connectivity to past learning is woven throughout.

The Concrete, Pictorial, Abstract (CPA) approach develops a deep understanding of math through building on existing knowledge. This highly effective framework introduces concepts in a tangible way and progresses to increasing levels of abstraction. In the concrete phase, students interact with physical objects to model problems. In the pictorial phase, they make a mental connection between the objects they just handled and visual representations of those objects. For example, real oranges (or counters standing in for oranges) are now represented as drawings of oranges. In the abstract phase, students use symbolic modeling of problems using numbers and math symbols (+, −, ×, ÷).

By varying the methods and phases of CPA fluidly, educators help reinforce important connections. Students work towards math mastery when they view concepts with increasing levels of abstraction over time. Not all lessons include all three CPA stages as application of this approach varies by topic. Instead, CPA principles are woven throughout the curriculum, and support other important strategies such as number bonds, bar modeling, and mental math. 

Singapore consistently ranks at the top in international math testing. The intentional progression of concepts in the Singapore math approach instills a deep understanding of mathematics.

Two international tests, the TIMSS (Trends in International Mathematics and Science Study) and the PISA (Programme for International Student Assessment), assess math and science competency in countries around the world. Singapore students consistently rank among the top on both tests. 

Our Singapore math programs raise U.S. student performance internationally and at home on standardized and state assessments. With the use of our programs, more students rank “At or Above NAEP Proficient” on U.S. national math assessments.*

Singapore Math Inc.

We started Singapore Math Inc. because we thought everyone should have access to this effective teaching approach. All of our programs preserve the techniques, sequencing, and rigor that define Singapore math. We continue to provide the original curriculum that put Singapore math on the map, while evolving the Singapore math approach through other series to better serve today’s students and educators.

In U.S. math programs, concepts and skills are more compartmentalized within and across grade levels than in Singapore math, where a strong sense of connectivity to past learning is woven throughout.

We believe the highest quality math education should be accessible to all. Our commitment to this mission began over twenty years ago when we introduced the world to Singapore math, and it remains our guiding principle as we develop new and affordable Singapore Math® programs.

When we moved from Singapore to the U.S., we found our daughter’s public school math program lacking. We began to supplement her education with the math curriculum used at her previous school in Singapore. Through this process, we realized that the Singapore math method was uniquely effective and that it would be useful to other parents and teachers in our community. We started selling the original Singapore Math program, Primary Mathematics, from our home in 1998 to share this powerful approach.

Since those early years, Singapore math has become an established part of national and international conversations about math education. We’ve continually improved and expanded our programs to suit the diverse and ever-evolving needs of U.S. students and educators. Our latest series, Dimensions Math® PK-5, takes what we love about the Singapore math approach and makes it more accessible, affordable, and engaging to today’s students and educators.

One thing that will never change is our core belief that everyone deserves an excellent math education, regardless of their situation. We know that a foundation in Singapore math creates the conditions for future success, and our goal is to make the finest math education in the world available to as many students as possible. We intentionally develop and price all our offerings with this in mind.

Thank you for growing with us as we raise math standards for all!

Sincerely,
Jeffery and Dawn Thomas
