Final answer:
The reference information provided does not contain specific details about a character named Charlotte, making it impossible to accurately answer the question about her first-day-of-school desires for her homeroom class to know.
Step-by-step explanation:
The information provided does not directly address “Charlotte” or her specific desires for what she wanted her homeroom class to know about her on the first day of school. Instead, there are multiple narratives and characters, including a story about a gym class, a recollection from junior high school about academic challenges and preferences, attendance rules discussed by a principal, a choice between regular school or a school for people with disabilities, and various literary excerpts. To provide an accurate answer to the question asked by the student, details about “Charlotte” specifically would be needed, which are not contained in the reference information given.
