Mixing Groups Systematically

Back in teacher's college one of my professors introduced me to a system for arranging groups of students in a class of 30. It was designed so that each student would have a chance to work with every other student once, but would never work with the same student twice. After the thrill of baring witness to such an elegant system subsided, I decided I could make it a little better. So a few years ago I had a go at applying the same concept to classes of different sizes. More recently I used some recently acquired skills in Sheets to make the system a bit more user friendly. The end result is three separate sheets that can be used for groups of 9-18, 20-24, and 25-28 students.

Here's how to use them for groups of three or more:

1. Enter the student's names in the boxes that say 'Student 1', 'Student 2' etc.
2. Enter the roles for students to play in the boxes that contain the letters A, B, C etc.
3. Select a mix number from the drop-down box, increasing it by one every time you want to change groups.

How to use it for pairs:

1. Enter the student's names in the LEFT HAND COLUMN ONLY.
2. Select a mix number from the drop-down box, increasing it by one every time you want to change pairs.
