One child is the ticker (giant) who sits in his house, the rest of the children are the gnomes and sit in a circle (with a small opening).
The giant comes out of his house and rings the doorbell of the gnomes and says "gnomes are you coming to play?" gnomes shout "NO!" The giant goes back home and goes to sleep.
One of the gnomes designated by the teacher walks to the giant's house and rings the bell: "giant are you coming out to play?" the giant sleeps on.
The gnome taps the nose of the giant.
The giant wakes up and yells "YES" and runs after the gnome.
The gnome goes back to his spot through the opening of the circle before he is tapped by the giant.
