How?
Fold arm over arm and lift right arm up and down from elbow like a tick tock of a clock
Point to children being named
Action hands together for washing hands
Why?
Marker for transition
Adaptable to other actions, e.g. time to go outside, time to put on hat
Repetitive simple language
Rhythmic and regulating and anxiety reducing for transition times
 
*This is a great song for transition times
