Why was this book born? There are several reasons. The main thing is that for many years our schools have received not textbooks, but peculiar guides that do not teach children, but show what children should know and be able to do. Who teaches them? Moms and dads, grandparents, tutors and teachers teach. Anyone trying to help children has to invent a textbook. The knowledge and experience of mentors is different, which means that the training of children, especially in the lower grades, does not lend itself to any standardization. Usually, by grade 5-6, most children develop a stable aversion to learning languages. The authors of these colorful guidebooks declare that they are not self-taught. Practice shows that these are not textbooks.
