When a teacher assigns an Objective as a class assignment only, only students who haven't played it so far this year will be prompted to play it. In other words, Class Assignments are like a task list. If a student has completed that task already, the Objective is checked automatically and the student moves on to the next activity. You can assign an Objective to your class by selecting the class, going to Objectives > Assignments, and clicking 'Add'.
When a teacher assigns an Objective as an individual assignment, that student will be prompted to play that objective, even if they've played it before. Students earn puzzles when they replay content, even if they've completed it previously. This is a great way to have a student review material they might need a refresher on. Students will not retake the quiz for a reassigned objective.
All objectives assigned as a class or individual assignment count toward a student's percent progress, but only objectives part of a student's journey count toward their Journey progress.

Class assignments appear under students My Classes assignments, and individual assignments appear under Just for me. For steps on how to assign class or individual assignments visit: How do I assign, edit, or reorder class and individual assignments?
