Primary Mathematics is the original Singapore math curriculum we introduced to the U.S. in 1998. Written by the Singapore Ministry of Education, it was the series in use when Singapore garnered attention for scoring at the top of international math tests.
Primary Mathematics epitomizes the Singapore Math Approach. The curriculum features the CPA (Concrete, Pictorial, Abstract) progression, number bonds, bar modeling, and a strong focus on fact fluency and mental math. The curriculum balances supervised learning and independent practice. This rigorous program encourages active thinking, communication of mathematical ideas, and problem solving. It lays the foundation students need for more advanced mathematics.
Take a Look Inside
Common Core Edition
We carry three editions of Primary Mathematics. All maintain the integrity of the Singapore Math Approach while serving diverse needs.
Primary Mathematics U.S. Edition
This edition is almost identical to the original program used in Singapore with additional content on U.S. measurements and currency.
Primary Mathematics Standards Edition
Written to meet the 2006 Mathematics Contents Standards for California Public School issued prior to the Common Core State Standards, this edition includes probability, data analysis, negative numbers, and coordinate graphing.
Primary Mathematics Common Core Edition
Released to align with Common Core State Standards, this edition has minor changes to the scope and sequence but is otherwise interchangeable with earlier editions. The format for the Teacher's Guides is updated to include student materials, making them wraparound guides.

Textbooks present new concepts and learning tasks for students to complete with educator supervision, along with practice and review problems. They are designed to be non-consumable and used alongside workbooks. There are two textbooks (A and B) for each grade corresponding to the two halves of the school year.
Workbooks provide additional practice and independent work to solidify the concepts covered in the textbooks. There are two workbooks (A and B) for each grade corresponding to the two halves of the school year.
Teacher's Guides help educators understand course material within the larger framework and prepare for lessons with detailed, step-by-step plans.
Home Instructor Guides are designed for homeschool use. They provide suggestions for introducing new concepts concretely and using textbooks effectively. They include additional activities for reinforcement, solutions to textbook and workbook problems, and suggested weekly schedules.
As the educator plays an active role in Singapore math programs, it is highly recommended to use a Teacher’s Guide or Home Instructor Guide.
Test books with differentiated assessments help teachers systematically evaluate student progress.
