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.
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 an active thinking process, communication of mathematical ideas, and p. 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.
