There are various ways to go about this, but the following way is the one that I prefer:
1. Open up a Word document, Notepad or a similar text editing program into which you can paste some URLs.
2. Go to Topic 1, and right-click on the first resource or activity.
3. Click on Properties.
4. Copy (Ctrl+C) the Address or the URL that will appear, and then paste it (Ctrl+V) into your text document.
5. In your text document, type a name to remind you which resource or activity the link was for.
6. Repeat this process with all of the resources and activities in topic 1.
7. Keep your text document safe, and scroll down to the bottom of the final topic.
8. Under Add a resource, choose Compose a web page.
9. Type in an introduction to the topic and paste in the resources and activities hyperlinks from your text document, making sure that they open in a new window.
10. Save it and display it. It will look something like this:
