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