Mathematics. 5th grade. Mental arithmetic. Developing computational skills in mathematics education.

This book is the first in a series of publications aimed at developing computational skills in grades 5-9. Teachers are recommended to use books from this series in conjunction with the books "Developing Computational Skills in Mathematics Classes in Grades 5-9, in Grades 10-11" by the same authors, as they reflect the concept of using mental arithmetic in teaching mathematics.
The manual is based on years of experience and presents a methodology for developing computational skills and mathematical abilities, unparalleled in methodological literature. It includes a complete set of level-based tests for assessing skills in operating with numbers and expressions based on definitions, rules, and properties, providing control, diagnostics, training, and materials for correction in the 5th grade.
The manual will allow for systematic work with students in forming basic mathematical knowledge. It will greatly assist students looking to enhance their effectiveness in learning mathematics, as well as parents monitoring their children's development.
The book is intended for mathematics and physics teachers, students in primary school, tutors, parents, and students in pedagogical universities.
