The Announcements feature of Canvas allows you to post information publicly in your course. Posting Announcements is a quick and easy way to communicate with all participants in your class. The information you post can then be easily referenced from the Announcements navigation link on the left-hand side menu of your course.
To make an announcement, complete the following steps:
Click on the Announcements tab on the left-hand side menu of your course.
In the top-right corner of the page that opens, you will see the Make an announcement option. Click on this option, and a page will open up with the Rich Content Editor.
In the Topic Title bar at the top of the new announcement, type in the title of the announcement you would like to make.
In the textbox of the Rich Content Editor, enter the information you would like to post publicly within your course.
You can add an attachment using the option below the textbox, and you can adjust the options as you see fit for the announcement...
