There are two ways to view answers to assessments: through the assessment's settings and in the Teacher Sidebar.
The answers for any quiz-type page (including Lesson Practices and Fast Starts) can be found within the item's settings. For clarity, this is for any of the pages that are indicated by the rocket icon on the Modules page as shown below.
To view the correct answers, complete the following steps as shown in the GIF below.
Click on the item you wish to view
Click the "Edit" button
Click the "Questions" tab
Check the "Show Question Details" box to show the answers
The second way to see the answers is through the Teacher Sidebar. Click the sidebar icon to display the links to the downloadable versions of any major quiz or exam as shown below. Please note that Lesson Practices, Review Questions, etc., are not major assessments and you will need to use the first method to view the answers to these items.
