## School FAQ

Take a look at sample pages from Dimensions Math and Primary Mathematics to get a feel for each program.

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. Unique Singapore math methods, such as number bonds and bar modeling, also set Singapore math apart from typical U.S. math pedagogical styles.

Dimensions Math includes expanded teaching materials, here on our Resources page, such as videos, Blackline Masters, letters home, and more.

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.

We started Singapore Math Inc. over 25 years ago because we thought everyone should have access to this incredibly effective teaching method. Please read Our Story for more.

Singapore math programs do not continue beyond Grade 8. Students may move onto Geometry and Algebra 2 but we do not have specific recommendations for curricula.

Yes, with fully worked solutions for many of the problems. The Home Instructor's Guides and Teacher's Guides have answers for both the Textbooks and Workbooks. They also include lesson notes and suggestions. If you only want answers to the Workbook and Textbook problems, you can get the Answer Key Booklets (there's one for Grades 1–3 and one for Grades 4–5).

We don’t recommend using the Workbooks by themselves as you and your student will miss most of the core material, explanations, exercises, and teaching notes.

Primary Mathematics has four editions: U.S. Edition, Standards Edition, Common Core Edition, and the 2022 Edition.

Primary Mathematics U.S. Edition
Almost identical to the original program from Singapore, but uses U.S. measurements and currency.

Primary Mathematics Standards Edition
Written to meet the California Public School standards prior to Common Core, this edition includes probability, data analysis, negative numbers, and coordinate graphing.

Primary Mathematics Common Core Edition
Aligns with Common Core. This edition has changes to the scope and sequence.

Primary Mathematics (2022 Edition)
Content and lesson structure is entirely new. More differentiation and more aligned with U.S. school standards.

Letters Home and other Dimensions resources are on the Dimensions Math PK-5 Resources page. They're organized by grade level.

The content was created by our team of teachers and experts with over 100 combined years of Singapore math classroom experience. The series was designed and published in-house by Singapore Math Inc.

Lessons begin with a class activity to encourage discovery. Worked examples of new concepts are followed by similar questions for students to solidify their understanding.

Exercises include:

• Basic Practice: Simple questions that drill comprehension of concepts
• Further Practice: More challenging questions that involve direct application
• Challenging Practice: Questions that require synthesis
• Maths@Work: Questions that apply mathematical concepts to real world situations
• Brainworks and Enrichment: Questions involving higher order thinking or an open-ended approach to problems

Each chapter in Grades 7-8 is followed by a review exercise. The Extend Your Learning Curve activity encourages students to consider math outside the classroom with questions requiring sentence or paragraph reflections on their learning experiences.

As in all our programs, the school year is divided into two semesters: A and B. A books cover the first half of the year, and B books cover the second half of the year.

Grade 6 includes (A and B) Textbooks, Workbooks, Teacher’s Guides, and Workbook Solutions.

Grades 7-8 include (A and B) Textbooks, Workbooks, Teaching Notes and Solutions, and Workbook Solutions.

The Dimensions Math 6-8 program brings the Singapore math approach to middle school, emphasizing problem solving and empowering students to think mathematically. This rigorous series integrates pre-algebra, algebra, geometry, some trigonometry, and advanced math topics. Learn more here

Dimensions Math 7 and 8 together cover Pre-algebra and Algebra 1 topics, with some geometry. Dimensions Math 6 is aligned with Common Core Standards, and so while it does include some Pre-algebra topics, it is not a Pre-algebra text in the traditional sense. It is a Grade 6 text.

Dimensions Math 7 assumes students are new to Pre-algebra topics, such as integers and simple algebraic equations, but goes farther into Algebra topics than would a traditional Pre-algebra text. Therefore, Dimensions Math 8 has greater expectations for what students have covered previously (particularly with regard to linear equations) than a traditional Algebra 1 text. The two grades, 6 and 7, are meant to be done as a set.

After grade 8, students may move onto Geometry and Algebra 2 programs.

Both are highly effective Singapore math programs. They are more similar than they are different.

They both follow the Singapore math approach, which emphasizes the CPA (Concrete, Pictorial, Abstract) progression, centers the use of number bonds and bar models to solve word problems, and encourages mastery of mental math to gain number sense, computational fluency, and logical thinking.

If you're trying to decide between the two programs, you may find this helpful: Dimensions or Primary?

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. 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. 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 Textbook and Workbook pages for easy reference to every lesson. The Teacher’s Guides give more ideas for differentiation and include math literature suggestions.

Yes, you need both Textbooks and Workbooks to successfully use the Dimensions Math curriculum. They are designed to be used together and the program is incomplete if one is left out. Textbooks introduce concepts and are central to learning and understanding new topics. Workbooks provide practice and independent work, which is essential for solidifying new knowledge.

The school year is divided into two semesters: A and B. There are A and B Textbooks, Workbooks, Teacher’s Guides, and Tests for each grade. Textbooks, Workbooks, and Teacher's Guides are necessary to successfully use this program. Tests are optional. Note that there is only one Tests book for Grade K, and none for Grade PK. There's also a Dimensions Math video subscription. Free Dimensions Math resources, such as Blackline Masters, can be found here.

We offer free placement tests. If you're new to Singapore math, we highly recommend giving your student a placement test to be sure they start at the appropriate level.

While we don’t offer professional development directly, we recommend the following trainers and training companies who have experience with Singapore math.

Here's a great introduction (PDF). We created Dimensions Math to better serve teachers and students. We preserved all the methods and content that make Singapore math so effective, while making improvements to educator resources, design, and more. Concepts are presented in a new format with vibrant imagery, while the progression and scope that define Singapore math remain intact. This is our most substantial program yet. Take a look inside each book of the program here.

Primary Mathematics 2022 Edition is a K-5 program written to align with U.S. standards while reflecting current practices of math instruction in Singapore. The content and lesson structure are completely new and do not resemble those of previous Primary Mathematics editions.

Like previous editions of Primary Mathematics, the program builds strong problem solving, critical thinking, and computational skills through classic Singapore math methods, such as the concrete-pictorial-abstract approach and bar modeling.

Singapore has consistently ranked at the top in international math testing for decades.

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.
