Primary Mathematics for Homeschool

Primary Mathematics is the curriculum that originally put Singapore at the top of international math tests. This renowned series has over two decades of proven results in the U.S. There are currently four editions of Primary Mathematics.

Primary Mathematics epitomizes what educators love about the Singapore math approach, including the CPA progression, number bonds, bar modeling, and a strong focus on mental math. It's a no-fuss, straightforward program that balances supervised learning and independent practice.

The recently released Primary Mathematics 2022 Edition is just beginning to be explored by homeschoolers. This edition uses the same approach as previous Primary Mathematics editions, but features entirely new content and lesson structures.

2022 Edition

Marks a departure from previous Primary Mathematics editions with entirely new content and structure. More aligned with U.S. school standards and provides more differentiation opportunities.


U.S. Edition

The most popular edition among homeschoolers. Almost identical to the original program used in Singapore, but with U.S. measurements and currency.


Common Core Edition

More closely aligns with Common Core State Standards. This edition has minor changes to the scope and sequence, and the format for the Teacher’s Guides is updated to include student materials.


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.


Components of Primary Mathematics (2022 Edition)

Student Book

The consumable Textbook of the program. The Student Book equips students with strong conceptual understanding, critical thinking, and problem-solving skills. Mathematical concepts are developed in a clear and sequential way to facilitate understanding.

Additional Practice

The Workbook of the program. Additional Practice provides students with on-level practice of concepts and skills.

Mastery and Beyond

A new student workbook based on extensive research about how students consolidate knowledge, Mastery and Beyond provides distributed practice. Together, the Student Book, Additional Practice, and Mastery and Beyond are designed to develop fluency and flexibility in math.

Teacher’s Guide

The Teacher’s Guide provides teaching ideas and strategies to facilitate exploration, classroom discussion, and student-centered learning. It also includes ideas for differentiation, ideas for small group learning, and answers with select worked solutions. The front matter provides background on the program structure, lesson and concept development, and an overview of the Readiness-Engagement-Mastery model of learning.

Home Instructor’s Guide

Intended to accompany the Student Book, the Home Instructor’s Guide provides Student Book answers, select worked solutions, teaching ideas, and strategies to facilitate exploration, discussion, and student-centered learning. The front matter provides background on the program structure, lesson and concept development, and an overview of the Readiness-Engagement-Mastery model of learning.

Assessment Guide Teacher Edition

A tool for teachers to assess student learning and progress. There are chapter tests, cumulative assessments, and mid-year and end-of-year assessments.

Components of U.S., Common Core, and Standards Editions


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.


Workbooks provide additional practice and independent work to solidify the concepts covered in the textbooks

Teacher’s Guide

Teacher’s Guides help educators understand course material within the larger framework and prepare for lessons with detailed, step-by-step plans.

Home Instructor’s Guide

Home Instructor’s 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.
