One boy had a birthday (4 years old). A crowd of the same carapuses 3-4 years old.

The animator leads the party and says: guys, why are we all here? The children are a little dull and silent, looking at the animator with interest. The animator decides to suggest and continues:

Maybe today is New Year?

No is!

Maybe today is March 8th?

No is!

What is the celebration today? Let’s talk together, three or four!

All the children are chorus:

Three or four!
