Get rid of any tables and chairs.

Get the kids together in one big group.

Have the kids move around, mingling with each other.

The kids ask you a question that you can answer with a number e.g. “What’s the time?”

You answer and the kid gets into groups of that number e.g. you say "It’s 4 o’clock" and the kid gets into groups of four.

You can change the verb any time you want to play while the kids move around, mingling with each other.

E.g. "swim" where the kids swim around whilst mingling, or "dance" or "hop".
