There you will see the titles of the Pages you created. Hover your mouse over them and click one then look up at your top browser bar. You will see a URL with a numeric ID at the end. This is the page ID. Leave this open.
Now open another tab or window, log-in and go here > Appearance > Widgets
Drag the Pages widget out of the Available widgets box and drop it into the Sidebar box.
Click it to open it and you will see this:
Page IDs, separated by commas.
Delete | Close
Type the Page ID number you saw in your browser in the other tab into the space where I indicate with bold letters above followed by a comma,
Go back to the Edit pages screen and repeat the same process for every Page you want to hide.
When you are done click "Save" and then "Close" on the widget.
Close the other pages edit screen tab.
View the front of the blog to see that the Pages are now hidden.
