In compiling the Primer, the author used his 30 years of experience as a speech therapist, which for the first time allowed to combine literacy training with the prevention of errors in writing that occur at school age. ABC is based on the traditional approach to learning to read in Russian, complementing the traditional approach of the original way of teaching the child to understand the letter combination as a whole graphic element — syllable as a unit of reading (hereinafter letters). The primer does not have an entertaining or entertaining character, its task is to provide the child with the fastest mastery of the reading technique, which should bring joy and pleasure to children as a reward for their work. We hope that our children, having mastered reading without much difficulty, will take up the book as a tool of culture and a source of knowledge.
