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, communication of mathematical ideas, and problem-solving. This helps develop the foundation students will need for more advanced mathematics.
The workbooks are consumable and should be used in conjunction with the textbooks. They contain the exercises the student does independently.
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 key booklets are also available for purchase: one for Primary Mathematics 1–3 and one for Primary Mathematics 4–6.
Students who switch to Primary Mathematics from another curriculum may not have the necessary background to begin at the level corresponding with their grade level without review from earlier levels. We suggest that you use these placement tests to decide where to place students new to Primary Mathematics, or to get an idea of which concepts may have to be reviewed from an earlier level.
