“The Journey of Leo to Tranquility” is an educational material specifically designed for autistic children, with the aim of improving their reading comprehension and life skills. The story follows Leo, a boy with a special love for puzzles and his cat, Puzzles, as he navigates his emotions and learns to manage stress. Through Leo’s experiences, children can identify with real-life situations, such as feeling overwhelmed by sensory stimuli and difficulties in expressing their emotions. The narrative addresses important topics such as recognizing signs of stress, stress management techniques like deep breathing, and the importance of asking for help. At the end of the story, reading comprehension questions are included to reinforce learning and encourage discussion. Additionally, drawings related to the story are provided to help children visualize and discuss the scenes, thus promoting their ability to interpret emotions and social situations. This material is a valuable tool for parents and educators looking to support the emotional and social development of autistic children.
