Log into Canvas

In the Global Navigation menu on the left hand side click 'Courses'.

On the pop-out scroll to 'All courses' and click the link.  Here you will see all the modules you're enrolled in.  

You can add modules to your Dashboard by clicking on the star next to the module name. When the star changes to the colour Orange it will be added to your Dashboard.

If you are unable to select the star, check the 'Published' column.   If the module is not published please speak to your tutor who will be able to publish the module.
