There are two ways to create an individual or small group assignment:
1. When creating an assignment, under "Assign this text:" choose "To one or more individual students" and manually select each student. This assignment will be listed on your Assignments page under "individual and Small Group Assignments."
2. Create a class-wide assignment as usual and then exempt the students not taking it from the Assignment Report. You can get to the Assignment Report for a new assignment with no submissions by going to My Dashboard > Assignments > Dashboard (for the particular assignment) > Assignment Report (link on the lefthand side). Scroll to the bottom and use the checkboxes under the "Incomplete Assignments" list to exempt students.
The benefits of creating a class-wide assignment and exempting students include the ability to reassign the text to students later, keep your assignment better organized, and allow these assignments to appear on your Student Progress pages.
