Post an answer key online or somewhere in the room.  Students use it to quickly compare their work to the correct answers.  Rather than calling the answers aloud to the whole class, this lets students check their work quickly and quietly.

 

 Then you can go over commonly missed problems.  This process alone does not drive the learning very deep but does make in-class grading more efficient so it takes less class time.  Follow up with an Error Analysis to drive the learning deeper.
