Dimensions Math, Primary Mathematics U.S. Edition, and Primary Mathematics 2022 Edition are the three programs that schools most commonly use. (Primary Mathematics Common Core and Standards Editions are very similar to the U.S. Edition with minor differences to align with specific standards.)

This page offers a brief overview of each program with some thoughts and suggestions from math teachers, curriculum advisors, and professional math trainers.

• Your student is generally competent in math and hasn't struggled with the topic much in the past.

• Teachers are often wary at the point of adoption. The first year is about getting their bearings, the second year is more enjoyable, and by the third year, almost every single teacher will be a convert and devoted to Singapore math from that point on. They've deepened their own knowledge of math and have come to see how effective the methods and material are. If math wasn't their strong point before, it might become their favorite subject.

• 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 a typical U.S. student, but still cover the Common Core Standards, though sometimes in an earlier grade level.

• You want the option to add a video subscription that covers each lesson very comprehensively.

• 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 an 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 struggles 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, it can be used for all levels of ability and includes differentiated learning pathways.)

• You prefer to follow more scripted lesson plans without the need to modify much for ability.

• 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, social and emotional learning, and preparing students for twenty-first century competencies. 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.
