Singapore 4B One-Semester Set

The Primary Mathematics U.S. Edition® series of elementary math textbooks and workbooks is meant to be part of a system of learning in which adult supervision and independent practice go hand in hand. The main feature of this series is the use of the Concrete to Pictorial to Abstract approach. Students are provided with the necessary learning experiences beginning with the concrete and pictorial stages, followed by the abstract stage to enable them to learn mathematics meaningfully. This approach encourages active thinking process, communication of mathematical ideas and problem solving, which helps develop the foundation students will need for more advanced mathematics.

Practice exercises are designed to provide the students with further practice after they have done the relevant workbook exercises. Review exercises are provided for cumulative reviews of concepts and skills. All the practice exercises and review exercises are optional exercises. - from the Preface

The textbooks contain the learning tasks for students to do under adult supervision and interaction, along with practice and review problems. They are meant to be non-consumable and to be used along with the Primary Mathematics Workbooks.

The workbooks are consumable and should be used in conjunction with the textbooks. They contain the exercises the student does independently.
