Hi @CynthiaLogan ,
In your title you mention Modules, but in your text you ask about Pages. @emily_beckman showed you how to add hyperlinks on a Page. But if you are using Modules, you can link directly to your documents in the Module. When you add an item to the Module, select "External URL" from the drop-down menu. For a Google Doc, you will use the Copy Link feature and just copy that into the URL box. I don't use OneDrive in this way but assume it has a similar feature.
How do I add an external URL as a module item?
When your students access the Module, they will be able to click on the links there and be taken to the files.
Either method works; it is personal preference as to how you want your students to be exposed to and access the links.
