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> Pictorial>Abstract approach. The 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. This 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.

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 1-3 and one for Primary 4-6.
Primary Mathematics U.S. Edition 1A-6B is ideal for both classroom and home use for 1st – 7th grades. 1A is suitable for 1st-2nd grades. This is the most popular (Singapore Math) primary math series used by schools and homeschoolers in the U.S. and Canada.
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 Guides too, because there are solutions in the Guides.
Home Guides are best suited for home use.
