Dimensions Math for Schools

Dimensions Math® PK–5 is our flagship Singapore Math® curriculum. With its rigorous content and engaging visuals, it's easy to see why it's our most popular program.

Written by a team of Singapore math educators and experts with more than 100 years of combined classroom experience, Dimensions Math PK-5 provides a deep elementary math foundation. This is a refined, comprehensive series that meets the needs of today’s students and educators. 


Textbook lessons build on prior knowledge and develop concepts in an approachable way. Textbooks A and B for each grade correspond to the two halves of the school year. 

1. Think: Stimulates interest in new concepts through a hands-on activity or problem. 

2. Learn: Presents definitions and fully explains new concepts. 

3. Do: Solidifies and deepens student understanding of concepts.



Workbooks offer independent practice through careful progression of exercise variation. Workbooks A and B for each grade correspond to the two halves of the school year. 

4. Exercise: Provides additional problems in the workbook for students to master concepts. 

5. Practice: Provides teachers with opportunities for consolidation, remediation, and assessment. 



Tests help teachers systematically evaluate student progress. They align with the content of textbooks. Grades 1–5 have differentiated assessments: Test A focuses on key concepts and fundamental problem-solving skills, while Test B focuses on the application of analytical skills and heuristics.
