Dimensions Math® PK–5

A refreshed approach to Singapore math from the people who know it best.

Written by a team of teachers and experts with more than 100 years of combined classroom experience, Dimensions Math PK-5 is an engaging curriculum for classrooms and homeschools that provides a deep elementary math foundation that serves students throughout their math careers. The price of the series reflects our belief that an excellent math education should be accessible to all.


Build on prior knowledge, and develop concepts in an accessible way. There are two textbooks (A and B) for each grade corresponding to the two halves of the school year.


Offer independent practice while maintaining the careful progression of exercise variation. There are two workbooks (A and B) for each grade corresponding to the two halves of the school year.

Teacher’s Guides

A comprehensive resource that help teachers understand the purpose of each lesson within the framework of the curriculum. They include detailed teaching notes and activities to achieve lesson objectives.


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.

Lesson Flow and Contents

Throughout the series, five characters offer suggestions on how to think about problems, remind students of strategies they’ve learned, and point out important information to encourage students to come up with their own solutions.

Lessons begin with a problem for students to solve, setting the stage for discussion. Students who need additional support can spend more time working with manipulatives or using other strategies as outlined in the Teacher’s Guide, while teachers can listen for common misunderstandings and encourage students to solve problems in various ways until they internalize concepts.

Once students have mastered a concept with the use of concrete and pictorial aids, they are ready to take on more abstract mathematical problem sets. They reach fluency by collecting various strategies along the way.

Finally, students work through word problems that give them a sense of real-world application of math. Students use the strategies they learned in earlier phases to both understand and solve these problems.

All lessons have a corresponding workbook exercise, which extends independent practice of mathematical concepts. A thoughtful progression pattern followed throughout the series covers the fundamental concepts, offers practice exercises with pictorial representations, and challenges students with abstract exercises.
