Armed with my trusty camera, I asked a couple of children to help me. The first girl is 3; the second girl is 4. (I apologize in advance for the pictures but this is a difficult activity to capture.)
First, the child spreads her coat onto the floor with the front open to expose the arm holes. She then moves the coat (or her body) to make sure the label is close to her feet (or knees if she is kneeling).
Then the child puts her arms as far into each arm hole as she can, holds onto the material........
...and then flips the coat up into the air and over her head and behind her back (which is why its important that the child hold onto the material inside the arms) .
The child then pushes her hands to the ends of the sleeves and shrugs the coat onto her shoulders.
In the classroom, I show the children how to do this with my own coat. I have done it as a group presentation but find a one on one presentation much more effective. I don't use a lot of words - in fact I don't use any - to give the child time to really observe what I am doing.
