Mixed Review is built automatically and incrementally. When a teacher clicks ASSIGN on an assignment, the skills included in the assignment are automatically added to Mixed Review for the class.
To add skills to Mixed Review, create an assignment, click ASSIGN, and check the class(es) that need the assignment. Choose ASSIGN to include the skills for your students' Mixed Review.
You also could choose to assign an assignment, and then immediately click SWITCH TO MIXED REVIEW to have the students practice the new skills in Mixed Review.
Don't forget to check the Mixed Review report for the class. You'll want to view Proficiency and monitor long-term retention of concepts.
