teacher,subject and which subject belongs to which class.
See my answer.

Start with requirements gathering and analysis with the users to find out, among other things,
1. Who and What are involved: Teacher, Student, Subject, etc => Entities
2. What are their relationships: e.g. every teacher can teach multiple subject, every teacher can teacher many students, etc => Relationship
3. What data do they capture, any system, documents (forms, letters) they use to do this job currently? => Reveal data attributes and existing work flow.
4. What are other other requirements.
It is impossible to explain the design of a database here, you may refer to Introduction to database design[^]. It is a matter of trials and errors, but you get better with more practice. Always go through your design with the users until they are satisfied.
