Hi @CarolJacoby349, glad to hear you're in the process of creating your course!
Most instructors will add resources relevant to each lecture, as this helps the student focus on the content they're learning on each section. However, there isn't a one-size-fits-all approach when it comes to adding resources to your lectures, but I'd recommend taking a look at this article to learn the best practices when outlining your course.
On your course landing page, it will display the number of downloadable resources you have across the entire course, so if you upload 10 spreadsheets, it will appear as '10 downloadable resources', regardless of adding it to one lecture or to multiple lectures. If you have any further questions, feel free to reach out to our Instructor Support team - they'll be happy to help! 😊
