My search for Halloween books that are simple, funny and have lots of language to discuss brought me to two more books that might be helpful to you.
Skeleton Hiccups by Margery Cuyler is a favorite as the skeleton goes through his day, waking up, taking a shower, brushing his teeth and polishing his bones, as his hiccups continue–hic, hic, hic. Each double page is so simple but there is plenty to talk about as his arm comes off while polishing or his jaw flies out as he brushes his teeth! Ghost helps out with several suggestions like drinking upside down and holding his breath. Finally, ghost reaches into his old trunk to get just the right thing to end the hiccups.
T. Rex Trick or Treats by Lois Grambling takes us through the tough process of T. Rex deciding on a Halloween costume. With lots of words in bold for pre-literacy such as EEK and SCARY, this book draws the kids into the story. The illustrations are cute, especially of his dream of being a bat or a black cat with whiskers taped to his nose!
I hope you all have your costumes picked out! Happy Halloween.
