Team / Classroom

Common Ground Grid

A team icebreaker where small groups race to find shared facts.

How to play

Simple rules

Have paper, printable ready before you explain the rules. Explain the goal in one sentence, run a short first round, then let the group settle into the rhythm.

Split into groups of three or four.
Each group draws a grid with nine squares.
Fill each square with something everyone in the group has in common.
Share the most surprising square with the room.

Best use

When this works well

Good fit

Use it when a group needs a practical warmup before a meeting, workshop, or shared task.

Maybe skip it

Skip it if the group is under time pressure or if the prompt could feel too personal for work.

Variation

Change the format

Require at least three squares that are not work-related.

Tips

Make it work better

Name the time limit clearly and keep the first prompt neutral so participation feels easy.
Keep the first round simple and treat it as practice.
Let players pass if they need a moment.
Stop while the activity still has energy instead of stretching it too long.
