The book "Learning and Practicing Mathematics in the 2nd Grade of Primary School (Volumes A and B)" is aimed at students, parents, and educators. The structure and organization of the book follow that of the corresponding school materials (Student's Book and Workbook) and work in parallel with them.
Volume A contains four units, which are divided into 28 lessons - chapters.

Each lesson consists of two parts:

• The "Learning" part, where the student approaches mathematical concepts and discovers new knowledge.
• It is accompanied by theory specifically designed for young students.
• It is reinforced with extensions and examples.
• The "Exercises for Solution" part, where the student internalizes the new knowledge and "builds" on it through visual exercises and problems.

The exercises have a progressive level of difficulty.
They are accompanied by examples that help understand the requirements.
They include topics from Mathematics competitions, adapted to the cognitive level of the 2nd grade.

The units are completed with review lessons - chapters that assess the knowledge of key points.
The solutions - answers to all the above are provided afterwards.
