Can you retell the story to someone at home? Make some puppets (paper ones are fine) to help you re-tell the story.
Make a list (on paper or out loud) of the words that rhymed in the story.
Nursery: Could you add your own animal and draw a picture of it, maybe you could use your RWI knowledge to write the initial sound?
Challenge: Can you add your own animal? What else might the witch have dropped and who might have picked it up? Can you draw a picture and label it or add a couple of sentences about it?
