The Globolino series 'Ach so!' deals with interesting topics that children (from 4 to 8 years) know from their everyday lives. Thanks to easy-to-understand, child-friendly texts at different levels of difficulty, the books are suitable for beginning and weak readers, but also for advanced readers. Important words are explained separately at the end of each book and help to increase vocabulary. In addition, numerous photos, drawings and pictograms are included. Thus, these books are not only suitable for reading aloud and on their own, but also offer plenty of informative pictures for the youngest children to look at.
