What it is

Singapore Math Inc. sells two main lines: Primary Mathematics (several editions, including the 2022 Edition) and Dimensions Math. Each grade is split into A and B books; the parent teaches from a Home Instructor's Guide or Teacher's Guide using the textbook, and the student then practices in a workbook. Lessons move from hands-on objects to pictures to abstract numbers.

Written by the Homebuilt team from the publisher’s own materials, checked September 2026. Prices and editions change, so confirm with the publisher. Learn more: Singapore Math Inc. home · Primary Mathematics 2022 Edition · Primary Mathematics Home Instructor Guides
