Why choose Primary Mathematics?

This is the series that originally put Singapore math on the map. Multiple editions suit diverse requirements.

Primary Mathematics U.S. Edition: Tried and true. Almost identical to the curriculum used in Singapore when Singapore rose to the top of worldwide student testing.

Primary Mathematics Standards Edition: Revised to meet the California Public School standards prior to Common Core.

Primary Mathematics Common Core Edition: Revised to more closely align with Common Core. (Please note, this series will be discontinued in October 2025.)

Primary Mathematics 2022 Edition: Focuses on U.S. standards alignment and differentiation. This edition marks a complete departure from prior versions, with refreshed design and all new content and structure.

Suggestions from our Head Curriculum Advisor

Some thoughts from Jenny Kempe to help you make the right choice for you and your student.

  • Your student is in Grade PK, K, or 1. This curriculum has excellent content for these early levels, and starting at the beginning sets students up for a cohesive and continuous experience with no gaps to fill later.
  • Your student is generally competent in math and hasn't struggled with the topic much in the past.
  • You've enjoyed using Primary Mathematics U.S. or Standards Editions in the past and want to continue with the same substance, but with additional resources and a more complete package.
  • You want a curriculum with built-in differentiation that doesn’t require additional resources and can be used flexibly with most levels of ability. (Please note, Dimensions Math PK-5 contains many practice problems to reduce the need for supplemental material. Students are not expected to do all problems in all lessons. Educators should pick and choose what's appropriate. See the page, Tailoring Instruction for Dimensions Math, for more information.)
  • You are mostly confident in your ability to teach math and to fit the curriculum to your student’s needs, or are willing to gain that confidence by studying the content and the guides.
  • You want your student to be exposed to more mental math strategies and a greater variety of problems, including more challenging ones.
  • You want your student to be more advanced in math than typical U.S. standards, often covering topics at earlier grade levels.
  • You want the option to add a video subscription that covers content from Grades 1-6 comprehensively and may be viewed directly by students or by home instructors who are looking for training.
  • You enjoy math yourself or want to gain more depth in your own understanding of math.
  • Your student is generally competent in math and hasn't struggled with the topic much in the past.
  • You want the “original” that has been around for the longest time and has been successfully used for decades.
  • You want the shortest lessons and workbook exercises. This is a concise and efficient program.
  • You are not concerned about Common Core Standards. (This was not written for U.S. standards. It was lightly adapted for currency and measurement from the Singapore curriculum.)
  • You are willing to supplement with additional resources for more practice and challenge as needed. (This is a relatively spare program as it was designed to give teachers in Singapore time to do their own additional teaching. There are many great supplementary options that complement this series.)
  • Your student has struggled with math and has difficulty moving to the abstract. Of our core programs, this one is most suitable for students who struggle with math because its scope, pace, and reviews make it a more manageable curriculum. Please note, Primary Mathematics 2022 Edition can be used for all levels of ability and includes differentiated learning pathways.
  • You prefer to follow more scripted lesson plans.
  • You want to cover only the topics covered in U.S. public schools for that grade level, but cover them with greater depth and understanding.
  • You prefer a holistic approach to math that's more integrated with other subjects with emphasis on growth mindset and social and emotional learning. This program includes journaling, self-reflection, and STEAM activities.
  • You are coming to Singapore math in Grades 4 or 5 and do not want to have any issues with transitioning from another U.S. curriculum because topics were not covered earlier.

Program FAQ

We're here to help you find the right Singapore math program for you and your student.

What type of student does well with Singapore math?
  • Students who like conceptual and creative problem-solving.
  • Students who enjoy a balance of instruction and independent thinking.
  • Students who are visually or logically inclined.

Most students have the potential to do well with Singapore math if they start early and are guided with dedicated instruction (meaning by educators who have taken the time to learn the content and who are willing to teach with fidelity).

What type of student might struggle with Singapore math?

Singapore math may be challenging for students who struggle with abstract thinking or who thrive on replication and repetition. It is likely not a good fit for students who are in Grade 4 or above and are already struggling with math.

Are there natural levels to switch to the Dimensions Math curriculum from another program?

Earlier is better. Grade 2 and lower are ideal. Grade 3 and above is definitely still possible with individual instruction to fill in potential gaps, or with a student who is already doing well with math. Please give a placement test if switching from any curriculum other than Primary Mathematics U.S., Standards, or Common Core Editions.

Switching Between Singapore Math Programs

It's easy to switch between Dimensions Math and the earlier editions of Primary Mathematics through Grade 5. Scopes and sequences are similar. Students would not need to take placement tests.

It's also fine to go from Grade 5 of Primary Mathematics U.S., Standards, or Common Core into Dimensions Math Grade 6.

It's not advisable to switch from Grade 5 of Primary Mathematics U.S. Edition to Grade 6 of Primary Mathematics Standards Edition.

Students can easily switch from Dimensions Math or earlier editions of Primary Mathematics to Primary Mathematics 2022. There may be some repition of topics.

Students switching from Primary Mathematics 2022 into Dimensions Math or earlier editions of Primary Mathematics should take a placement test to determine potential gaps.
