Group Size Wheel

The group size wheel picks how big the groups are before anyone knows who is in them, which is what stops the same friendship clusters forming every time.

Eight options, from pairs up to the whole class, including working alone.

The order matters more than it seems. If students know the group size in advance, they arrange themselves before you have finished the instruction, and the arrangement is always the same one. Spinning the size first, then forming groups, breaks that habit without anyone being singled out.

Once you have a size, the team generator does the allocation. Paste the register, set the number per group, and it deals everyone out with a cryptographic shuffle — considerably faster than counting round the room and immune to the quiet negotiating that happens while you count.

Keeping "work alone" on the wheel is worth doing. Group work is not automatically better than solo work, and a class that never draws it starts to assume otherwise.
