Games on the playground

It is the first week of school. I happened to be there in the afternoon to volunteer and while waiting I chanced upon a group of first graders playing an organized game on the field. The game seemed simple - everyone scattered around and then the teacher said "I want you to form groups of " and people formed those groups. Most came together in groups of the right number but there would always be a groups of the 'leftovers'. Leftovers - people that did not want to join a group, or be with boys/girls, or just cling to their best friend. However I kept seeing her tell them that no one won and they were all out. After two rounds I listened more carefully - the rules were -

1. Everyone had to be in the right count group or the whole class was out. So if the group number was five then everyone had to be in a group of five else noone won.
2. It was not - in groups of five, she always said in a group of at least five.

It took a couple of rounds for someone to suggest that they form one big group and they'd win. Simple.

Nice way to get the class to work together and be inclusive.
