Split your class into balanced random groups by size or by number of groups, in one click. Reshuffle any time and print the result. Free, no sign-up.
Grouping a class by hand is slower than it looks — counting off, balancing the numbers, making sure the same students are not always together. The generator above does it instantly: paste your list, choose whether you want a set group size or a set number of groups, and it splits the class into balanced random teams you can print or project.
Letting students pick their own groups tends to reproduce the same social clusters and leaves some students out; always assigning the same groups can entrench roles. Random grouping mixes collaboration, gives students practice working with everyone, and removes the awkwardness of picking teams in front of the class. Because it is one click, you can regroup often — different teams for different tasks — which is exactly what keeps collaboration fresh.
The tool distributes students as evenly as possible, so you avoid lopsided groups. If you need to keep certain students together or apart, generate the groups and then make one or two manual swaps before printing — faster than building the whole thing by hand. Rotating groups regularly also means any single random pairing matters less, since the teams change again next time.
Group generation pairs naturally with the random name picker for assigning roles within teams, the seating chart generator for arranging the room around the groups, and the classroom timer for keeping group tasks on schedule. Together they turn the logistics of collaborative work into a few clicks.
Left to choose, students group with friends, which reproduces the same social clusters and quietly excludes whoever is picked last. Random grouping breaks that pattern: it mixes who works with whom, gives students practice collaborating with people they wouldn't choose, and removes the sting of being unpicked. Over a term, rotating random groups also builds a classroom culture where students can work with anyone — a genuinely useful skill that self-selected groups never develop.
Random is the right default, but not an absolute rule. Sometimes you need to keep two students apart, ensure a struggling student has a supportive partner, or balance groups by skill for a specific task. The efficient move is to generate random groups and then make one or two deliberate swaps before printing — you get the speed and fairness of randomization with the judgment only you can apply. That is faster than hand-building balanced groups from scratch and still lets you place the students who need placing.
Good grouping is only half the job; how you structure the task determines whether the group actually works together. Assign clear roles, give each group a concrete product to produce, and hold individuals accountable for their part so no one coasts. A random name picker is handy for assigning roles fairly within each group, and a projected timer keeps every group moving on the same schedule. The tool forms the teams; your structure makes them productive.
Group work is not automatically valuable; students have to be taught how to do it, and the composition of groups is part of that teaching. Rotating random groups regularly gives every student practice working with a range of peers rather than the same comfortable partners, which is the only way collaboration skills actually develop. It also quietly builds classroom community, as students discover they can work productively with classmates they would never have chosen. Pair random grouping with clear roles, a concrete shared product and individual accountability, and group work becomes a setting where students learn to cooperate — a genuinely useful skill — rather than a chance for a few to coast on others' work.
There is no account and no limit. Groups are generated in your browser from your class list, nothing you enter is stored on our servers, and you can reshuffle and reprint as often as you need. Make new teams for every task, print the results to post or hand out, and never run into a signup or a fee. Chalkbox exists to turn the recurring logistics of teaching — grouping, seating, timing, picking — into a few free clicks that keep your class list on your own device.
The one small setup step worth doing is keeping your class rosters in a document you can paste from, so forming groups takes seconds even on a busy day. With the list ready, you can regroup on the fly — new teams for a discussion, different ones for a lab, fresh pairs for peer review — and never lose momentum hunting for names. That readiness is what turns random grouping from a good idea into an everyday habit, and frequent regrouping is precisely what builds students' ability to work with anyone in the room rather than only their usual partners.
