The books contain simple and original activities that help children: learn basic things related to their life, health, and safety, enrich and organize their experiences from the environment, expand their cognitive and language skills, build basic pre-mathematical concepts, become aware of the cycle of seasons and holidays, acquire the necessary cognitive and writing skills for their level. The activities follow a progressive difficulty level and systematically cover all areas of child development, according to the approved preschool curriculum by the Ministry of Education. With many years of experience in Preschool Education and being aware of the crucial importance of the child's first books for their future development, we have paid special attention to the approach of various concepts and processes. This approach is done in an original and enjoyable way through areas that are particularly beloved by children, such as play, literature, and art education. Thus, the child's cognitive powers are mobilized and learning becomes an exciting journey of colors that will delight both children and adults - educators or parents - who will work with them.
