I have recently come across the ideas of story sacks. My son was able to bring one home from school. It is normally a large cloth bag with a chidren's story book included with supporting materials, all related to the theme of the book.
The supporting materials can include factual and reference books, toys including soft toys and games which would all be linked to the children's story book.
Here are a few suggestions of story sacks you can create yourself using some of our toys from The Wooden Play Den.
