Fair Group Work: How to Split a Class into Random Teams

Letting students pick their own groups feels kind and reliably produces the same three problems: the same friends clump together, the same students are picked last, and the ability spread is wildly uneven. Random grouping fixes all three in about ten seconds.

Group size or number of groups?

Decide which you are fixing. If the task needs teams of four, set the group size and let the number fall out. If you need exactly six stations, set the number of groups and let the sizes flex. Most tools let you choose either — pick the one that matches your activity.

A simple, repeatable method

1. Enter every student's name, one per line.
2. Choose group size (or number of groups).
3. Generate — the tool shuffles and deals names evenly.
4. Read them out or project the result so it is visibly random.
5. Re-generate for the next activity so groups keep changing.

Handling the real edge cases

• Odd numbers out: most tools put the remainder in the final group, making it one larger. Decide in advance whether a group of five is acceptable or whether you would rather have one group of three.
• Keeping friends apart: random shuffling usually separates them, but not by guarantee. If two specific students must not be together, generate again or swap manually.
• Balancing ability: pure randomness ignores skill. For mixed-ability teams, sort students into bands first, then deal one from each band into every group.
• Absentees: remove absent names before generating so groups are not left short.

Why students accept it

The trick is transparency. When the whole class watches the names get shuffled and dealt, nobody can claim favouritism, and the "picked last" stigma disappears because nobody picked anyone. Re-randomising each activity reinforces that it is chance, not you.

More than just classes

The same approach works for sports teams, project teams, debating sides, and even splitting colleagues into breakout rooms — anywhere a fair, unbiased split beats a self-selected one.
