Hi Laura,
If you don’t want slider in blog page then you need to go to dashboard -> pages -> create a blog page and at the right hand side of the page there is template. select blog image large or blog image medium or blog full content display you want.
Then go to dashboard -> settings -> reading and leave default to post page as shown in this screenshot http://awesomescreenshot.com/02256h6d83 After this you will no see the slider in your blog page.
