Blackboard’s Bb Grader app allows faculty to grade Blackboard Assignments while on the go from their iPad. Just take a look at a few of the features:

• View all assignments submitted to the Assignment tool from all of your courses.
  Grade and annotate PDF, Word, Powerpoint, JPG, PNG and HTML files directly in the app.
• Use assessment rubrics
• Provide text, audio and video feedback to students
• Return graded assignments to students as you complete each one or all at once
• Track student progress using the Retention Center

It may just become your preferred way to grade. Bb Grader is iPad only. Sorry Android and iPhone users. Check out Bb Grader in action in the video below.
