What are groups?

A group is like a team of friends who all follow the same rules to play a game together.

Imagine you and your friends are playing a game where everyone has to do the same action at the same time, like clapping, jumping, or even just pretending to be a robot. No matter how many friends join in, you all still follow that one rule: do the same thing together. That’s what a group is, it's a bunch of things (or people) that work together using the same rules.

In a group, everyone has to play by the same rules. If one person decides to do something different, like spinning around instead of clapping, they’re not following the group’s rule anymore. But if you all agree to change the rule, like now everyone spins instead of claps, then that's still a group.

Groups can be as small as two people or as big as your whole class. And just like in games, groups can have different kinds of rules depending on what they're doing.
