You may be able to like replies posted to course announcements. Instructors can choose to allow all course participants to like replies, they can restrict liking to users with grading permissions, or they can turn off the feature for an announcement.
If the steps in this lesson do not match what is displayed in your student's course, learn how to like a reply to an announcement in the Announcements Redesign interface.
In Course Navigation, click the Announcements link.
Locate the reply and click the Like icon.
The Like icon displays highlighted, indicating you have liked the reply.
When a reply is liked, the Like icon also displays the total number of likes for all users.
If your instructor has restricted the liking option to only users with grading permissions, you cannot like your favorite replies. However, you can still view the total number of likes given to each reply.
