CLASA Group is proud to be at the forefront of publishing, uniting its recognized tradition in publishing children's and youth books with the innovative technology represented by Augmented Reality. Our goal is to provide parents and teachers with efficient tools to educate today's children. The app "Learning to write" is designed for children to work on gross motor skills in a fun and entertaining way. The game proposes to trace letters, numbers and shapes with the finger, to strengthen their recognition and incorporate the direction of the trace. In addition, the audio is included with the name of the letters and numbers in Spanish and English, to contribute in this way to bilingual education.
