The option to enable the new course page feature can be seen in the course edit screen. 

Just choose the course you want to create an individual page for, and mark the checkbox that says Course Page Enabled. Make sure to hit Save Course after making this change too.

Once you do this, navigate back to your classroom page and click on the Courses dropdown button. This is how you navigate to your new course page!

Course pages look very similar to a regular classroom page, however only students and parents within that course are able to see them and receive communications from them. Announcements, newsletters, and spotlights work very much the same, and each course page can have an individualized homepage, banner, color, and announcement feed.
