Here's a simple dribbling warm up that works even if you have a big group (our nursery squad has 30 players).
Every player has a ball. And ask them to dribble across the pitch and back. Encourage them to keep the ball really close to them (ask what's the difference between running with the ball and dribbling?).
Then say: there's four part of the foot you can use to dribble, who can name one? (It's inside, outside, sole, toes).
Then they dribble using that part of the foot. And ask the question again? etc.
End, with - let's dribble and add a trick? Who knows a trick? (Then they all dribble and try to do that trick).
Easy to do, lots of time on the ball, and can then transition into another game
