Thanks Mary and Scarlet! I did take part of your suggestions, but did the following:
- Added another topic/week to the coruse
- Moved all activities to the new topic/week
- In the Lesson, just typed the name of the activity, which then auto linked to the activity
- In the Course Settings, set the number of topics/weeks to the original number so students cannot access or view the topic/week that contains the activites.
So far, it works great!
