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.
The color patch is used to invite active participation from the students and to facilitate oral discussion. The students are advised not to write on the color patches.
Above extract from Preface of Primary Mathematics U.S. Edition (reproduced with the permission of the publishers).
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 nonconsumable and to be used along with the Primary Mathematics Workbooks.
Answers or answer keys for Primary Mathematics U.S. Edition textbooks and workbooks are found in the teacher's guides and home instructor's guides. Answer keys booklets are also available  one for Primary 13 and one for Primary 46.

Our recommendation:
Primary Mathematics U.S. Edition 1A6B is ideal for both classroom and home use for 1st  7th grades. 1A is suitable for 1st2nd grades.
Recommended for those who want a solid, basic math program with a proven track record and an emphasis on concept development, mental techniques, and problem solving. This is primarily a direct instruction program. Students are given several approaches for solving problems and are encouraged to discuss ideas and explore additional methods. Teacher's Guides are best suited for classroom use. Some school teachers use the Home Instructor Guides too, because there are solutions in the Guides.
Home Instructor Guides are best suited for home use.
