When you create a new blog, I recommend creating about a dozen "posts".
Each "post" can be a separate page.
When you initially save the pages, I suggest you name them '01', '02', '03', and the last page '12' (or whatever is the last number). Why this suggestion: Blogger seems to name the page using the first title. So using '01', '02' etc gives you shorter names. You can rename the page later when you actually use it.
Note that the last (newest) page you create will be the "home" page, i.e. page 1. So if you create a dozen posts, the most recent one will be the home page, and you will have 11 other pages available.
They can be "Saved as Draft" until you need them.
You can use a "Links List" which will show up in the right sidebar, where you can link to the individual pages. To create a Links section, use the "Layout" tab, then on the right select "Add A Gadget", then select "Link List".
