This material presents a simple and visually appealing story about Leo and his snack in the park, designed especially for autistic children and young people, with clear illustrations on each page that support understanding of the text and allow them to anticipate what is happening in the scene. Based on the reading, it works on different levels of comprehension (literal questions about what the text says, inferential questions to “read between the lines,” and vocabulary exercises with concrete words such as backpack, blue blanket, big tree, or gray clouds), as well as activities that connect Leo’s experience with the child’s own life (for example, whether they have had a picnic or how they feel about the rain), which supports language development, the expression of preferences and emotions, and the construction of increasingly complete sentences, both in therapeutic settings and in the classroom or at home with the family.
