By the end of the 1st grade of Primary School, students are able to communicate effectively both orally and in writing, consciously using the letters of the alphabet. As a continuation of this process, the book "A-B, 1-2 preparing for the 2nd grade" aims to bring the child into contact with a variety of textual genres (narrative, explanatory, descriptive, etc.), grammatical rules and syntax phenomena through exercises, examples and rules concerning declensions of nouns, adjectives, verbs, pronouns, prepositions, inflected parts of speech, punctuation, etc. This particular book is based on the material of the Language and Mathematics lessons of the 2nd grade of the Primary school, as provided for in the Analytical Curriculum.
