Russian spelling is easy! Tutorial

The manual is designed to teach Russian spelling of children primary (3-4 grades) and secondary school to help teachers and parents of schoolchildren. The manual can also serve as a self-taught Russian spelling and a systematic orthographic reference book for high school students, students or foreigners who speak Russian at a level higher than the basic one.
The manual has a practical purpose: teaching Russian spelling. In the main text, the formal grammar is represented by a minimum, without which the spelling rules would become incomprehensible or inapplicable.
All orthographs that are contained in the programs of the 4-6th grades of the Russian school are considered. They added high-frequency orthograms of adverbs from the program of the 7th grade.
Almost all the spelling rules of school textbooks have been revised and set out in a new edition. They are greatly simplified to facilitate their application in the real process of writing. Several new rules are also presented. Each rule is accompanied by instructions on how to use it in written practice (algorithms), which consist of simple one-three-step operations. Following the rules and algorithms followed by exercises and dictations of varying complexity.
