Customising unit names can make navigation easier for you, your students, and any co-teachers you may have in the Subject.
Locate the unit you want to rename and click the Edit button on the right side of the unit folder's header. If you don't see the button, then click the unit's name to reveal its contents and options.
The title in the header will turn into an editable text box. Type the new name in the box and then press Enter on your keyboard, or click Save Unit.
