Posts on other pages

All of the students in my school have a blog, mine is : gcevoices.com/jh/

Right now I have five pages: home, math & science, english & history, electives, and field experience.

These are also the five different things I blog about, and I would like to know how I can have different posts show up under these different pages. Right now everything I post goes under home. I am fine with everything going under home, but I would also like people to be able to filter by the subjects (pages) I have.

Thanks so much for any input! I’m new to WordPress and have looked my heart out to find how to do this!
