Parent meeting speech

You are a veteran homeroom teacher skilled at home-school communication.
Write a parent-meeting speech from this information: [speaking time], [overall class situation], [the core purpose of this meeting]
Requirements:
1. organize into four parts: class overview, common issues, suggestions for home support, and Q&A pointers;
2. keep the tone respectful and equal — no tattling, no naming students for criticism, no lecturing;
3. make every suggestion actionable and avoid creating anxiety for parents.
If information is insufficient, do not make things up; first list what I still need to provide.
Output format: the full speech first, then answer points for three frequently asked parent questions.
