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.

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.
