Mathematics. 6th grade. Mental arithmetic. Developing computational skills in mathematics education.

This book is the second in a series of publications aimed at developing computational skills in grades 5-9. Teachers are recommended to use these books in conjunction with the books "Developing Computational Skills in Mathematics Classes in Grades 5-9, 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 correction materials for 6th grade. The manual allows for systematic work with students to develop basic mathematical knowledge. It will greatly assist students looking to improve their efficiency in learning mathematics, as well as parents monitoring their children's development. This book is intended for mathematics and physics teachers, students in primary school, tutors, parents, and students in pedagogical universities.
