“The Mystery of Hidden Words” is a pedagogical tool specifically designed for autistic children, aiming to enhance both reading comprehension and social skills. Through the story of Tomás, a young boy struggling to understand the use of idiomatic expressions or double meanings in everyday language, children can relate and learn in an interactive way. The tale focuses on the challenge of grasping figurative language, something many autistic children might grapple with. The questions provided after the story are designed to reinforce understanding of the plot and encourage children to reflect on the underlying meanings of the expressions. Moreover, the drawing section offers an opportunity for children to visualize and reconstruct parts of the story, promoting social interaction with their caregivers or educators as they discuss and complete conversations. Overall, this material delivers a holistic learning experience, addressing both cognitive and interpersonal skills.
