This book is about a boy, Francisco, who is from Mexico and is starting the first grade in America. As he gets to the school on the bus with his brother, he gains a headache due to the increasing volume of kids speaking English and Francisco not being able to understand. Once he gets settled in his classroom, next to his desk there is a caterpillar, which becomes his salvation throughout the school year. He is unable to understand his teacher, or his classmates, which gives him headaches, so instead of trying to pay attention to the teacher, he day dreams of being with his papa in the fields, and focusing on the caterpillar. Art becomes his favorite subject, and would have a habit of drawing butterflies, even got his artwork posted on the board by his teacher. He made a friend, Arthur, who knows a little bit of Spanish, but they get in trouble from the teacher since they aren't speaking English. One day during recess, a bully named Curtis comes storming over claiming that Francisco had his jacket resulting in them getting in a fight. What happens with Francisco's artwork from the board, what happens with the caterpillar after it cocoons, find out by reading this story.
The majority of this book is split between words and pictures. One set of pages is just words, while the next set is a combination of both words and pictures. The pictures are done in a brighter color scheme, lots of oranges, reds, greens and blues. The pictures seem to be done by paints, but I'm not quite sure. This story has a couple Spanish words interwoven into the text, giving it a more authentic type of culturally diverse story. At the end of the book, a glossary is provided with definitions of the Spanish words that were used, which I thought was a really good idea. I think this story is a really good example of how Mexican students feel when they get integrated into the American school system. They have a very difficult time understanding what's going on, they can't speak their home language, they have a hard time making friends, and they struggle in school and end up falling behind or even words, forgotten. La Mariposa is a very authentic Mexican story and I really enjoyed the way the story was told in this book and would recommend it to any Spanish speaking students I might have in my classroom.
