Open space. A whistle helps.

How to play

The children stand in a big circle, all facing the same way round.
The leader stands in the middle and calls, "Fire in the mountain!" The children reply, "Run, run, run!" and jog round the circle. Repeat the call a few times.
Suddenly the leader shouts a number, for example "Four!"
The children scramble to make groups of exactly four, holding hands or linking arms.
Any children left without a complete group are out and come to help the leader judge.
Start again and call a different number.
As players go out, call smaller numbers. When only three are left, call "Two!"

The last two players are the winners.

Instead of sending children out, give them a point against; play five rounds and applaud those with none.
Call sums ("two plus one!") or say the number in Hindi or the local language.
Change the movement each round: hop, walk backwards, walk like an elephant.

Clear the space of furniture. No pulling or pushing anyone out of a group; a group that pushes is itself out.

Friends always stick together. Call numbers that split them, and add the rule that groups must mix boys and girls or classes.
Children who are out get bored. Make them the judges, or start a second small circle for them.

Time the round with the party timer, make chits or random teams with the chit maker, and keep the points on the scoreboard.
