Primary Mathematics for Schools

Primary Mathematics is the curriculum that originally put Singapore at the top of international math testing. Schools in the U.S. and beyond have successfully implemented the program for over two decades. We offer every edition of Primary Mathematics. Please contact us to discuss which is right for your school.

Standards Edition

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 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.
