While I’m still remembering my Halloween read alouds, I want to mention one of my favorites.  Room on the Broom combines great rhyming with enough repetition to keep even the youngest listener engaged.  The illustrations, by Alex Scheffler, are great and the story funny and sweet.  I read this to my pre-k and K classes.
Synopsis: A witch is flying on her broomstick with her cat and drops her hat.  A dog finds it but asks, “Is there room on the broom for me?”.  As the story progresses, the witch drops a stunning number of things and gives a ride to many different creatures.  When the witch’s broom snaps in half, all her passengers fall into a bog.  She flies into a cloud, only to meet a fierce dragon who wants to eat her.  All of her animal friends gather themselves together.  Covered with bog slime and stacked one on top of the other, they look so fearsome, they scare the dragon away.  Left without a broom, the witch and her friends make a brew and create a spectacular new broomstick with room for everyone.
