This is a game called “Cat and Mouse”.
Children sit in a circle. One child is chosen to be the cat, and another child is the mouse.
The Cat has to catch the mouse, and the mouse must run once around the circle, to where they were sitting.
Here is the chant the children will sing when the Cat is chasing the mouse (including the actions of the Cat and Mouse):
“Little Mouse, careful” (Both Cat and Mouse must walk slowly)
“Pussy Cat is coming” (walking is quicker)
“Quickly, mousey run away, pussy cat wants a meal today” (Cat and Mouse children must run).
