The Tool Menu can be customized by instructors or site administrators to modify the appearance of menu items in the site, including hiding or showing tools to site participants.

In Site Templates, some tools are hidden by default.  For example, in the Activities Menu template, multiple instances of the Lessons tool for each Week are hidden by default so that instructors can develop course content and make it available to students as the course progresses.  You'll need to show each hidden lesson page to your site participants.

Note: The Roster tool is hidden by default in ALL Course Site Templates because students would see a blank page when clicking on the tool.  Due to privacy restrictions, information contained in the Roster tool is restricted to site participants in the Instructor, Secondary Instructor, Teaching Assistant, Owner, or Administrator roles. (Access to official photos is further restricted to participants listed in SIS as instructors, secondary instructors, or teaching assistants for rosters containing those photos.)

There are two locations in Site Info where you can remove tools from your site: Edit Tools and Page Order.
