Starting from the dashboard, select your grade level course from the My Courses Widget.  

To locate your Teacher's Edition as well as important specific sections such as the Pacing Guide and Planners, use the navigation bar on the left to locate the Course Introduction folder. 

Within this folder you'll find that all Teacher Resources have a green icon and a green Teacher label on the resource card.

As you are using additional folders throughout the course, you'll find additional Teacher Resources listed with the same green icons and green Teacher label.
