Blogger default templates do not have numbered page navigation. But visitors need page navigation for reading all posts of your blog easily. So, you need a Numbered Page Navigation Widget for your Blogger Blog. I am providing a simple Numbered Page Navigation Widget here. I personally use this widget in my blogger blog!
HOW TO ADD THIS WIDGET:
1. Log in to your Blogger account.
2. Click on Layout option of your blog.
3. Click on Add a Widget option. A new window will appear.
5. Click on SAVE and check your blog!
