Absolute literacy in 15 minutes a day. Grades 1-4

The manual contains orthographic rules from the elementary school Russian language course that are most challenging for students in grades 1-4. The book consists of small sections that provide the name of the orthographic rule, the rule itself, and examples of its usage, as well as "dangerous" words to memorize. Blank lines should be used to write down similar words. By spending just 15 minutes a day on each orthographic rule, the student will quickly achieve excellent results and develop absolute literacy.
