Here are some ideas about it:
- Nice to meet you! (about myself)
- My portfolio (useful and necessary material for professional use: lessons' plans, programmes and planning, presentations, projects and so on)
- Achievements (things we are proud of: the results of olympiads and contests)
- Pupils' works (projects, compositions, essays and so on)
- Things to discuss (a kind of forum, if it is possible)
- Ask the teacher (for pupils and their parents)
- What's the news? (news page)
- Interests to share (hobbies and spare time)
- Photo album

It's only a sketch!
