Given the difficulties detected in the teaching-learning process of the Spanish Language, and particularly in the orthographic component in the second grade students of the elementary school "José María Pérez Capote", the author initiated this research with the objective of proposing a system of activities for the development of skills with the b-v inadequacies. For the development of the work, methods of the theoretical level were used such as: the analytical-synthetic, inductive-deductive, historical-logical, systemic-structural; methods and techniques of the empirical level such as: the pedagogical test, observation, documentary analysis, the criterion of specialist, pre-experiment, and of the mathematical processing, the percentage analysis.Its novelty lies in a system in which organized, varied activities are proposed, with illustrations, and supported by different teaching media, which make possible the transit through the three levels of assimilation of knowledge, motivating the interest of students. The components of the Spanish Language are integrated, using sentence completions, crossword puzzles and word searches related to b-v inadequacies.
