Singapore Primary Math: 4A Textbook
The Singapore Primary Math: 4A Textbook coincides with the 4B Workbook.
Each year of Singapore Math is divided into two semesters (A and B). Each semester requires both a textbook and a workbook. To complete a full year of math in level 4, you will need a textbook/workbook pair for 4A, and a textbook/workbook pair for 4B. The Primary Mathematics series ends with 6A/6B.

The Singapore math method is a highly effective teaching approach originally developed in Singapore. The Singapore method is focused on mastery achieved through intentional sequencing of concepts.
Some of the key features of the Singapore approach include the CPA (Concrete, Pictorial, Abstract) progression, number bonds, bar modeling, and mental math. Instead of pushing through rote memorization, students learn to think mathematically and rely on the depth of knowledge gained in previous lessons.
Singapore math not only helps students become more successful problem solvers, it helps them gain a sense of confidence and resourcefulness because it insists on conceptual depth. This naturally prepares students to excel in more advanced math.
With Singapore math, students must think through concepts and apply them in new ways from the very start. Since they can’t rely on simple replication, students are pushed to greater engagement and broader thinking. Singapore math programs raise U.S. student performance internationally and at home on standardized and state assessments.
