Random Group Generator

Fair groups in one click — with keep-apart rules for the pairs you already know about.

Group work without the eye-rolls

Every teacher knows the two hard parts of group work happen before the work starts: making the groups fair, and keeping certain students apart. This free random group generator does both. Type your roster once — it's saved in your browser and shared with the rest of Class Zone — choose whether you want groups of a fixed size (say, fours) or a fixed number of groups (say, six teams), and click Generate. Sizes are always balanced so no group is stuck with one extra or one short by more than a single student.

Keep-apart rules that actually hold

Click a couple of names into the Keep apart list and the generator places those students in different groups. Add as many pairs as you need. If the pairs you've listed genuinely can't all be honored for the number of groups you asked for — three students who all must be separated, but only two groups — the tool doesn't fail silently: it produces the best arrangement it can and prints a clear note listing exactly which pairs it couldn't separate, so you can bump the group count and re-roll.

How teachers use it

The Re-roll button reshuffles with the same settings, so if a group doesn't feel right you're one tap from a fresh draw. And because the roster is shared, the same class powers the random name picker and the seating chart generator.

Frequently asked questions

Can I keep two students apart?

Yes. Add any number of keep-apart pairs and the generator will place those students in different groups. If a rule set is impossible for the group count you asked for, it does the best it can and tells you exactly which pairs it could not separate.

Groups of a certain size, or a certain number of groups?

Both. Switch between 'Groups of N' — for example groups of 4 — and 'N groups' — for example 6 teams. Either way the tool balances the sizes so they differ by at most one student.

Is my class roster stored anywhere?

Only in your own browser on your own device. Your roster is shared with the other Class Zone tools but never uploaded — there is no account and no server.

Can I print the groups?

Yes. Click Print for a clean black-and-white group sheet with no nav, ads, or controls — just the group cards, ready for the wall or a handout.
