I highly recommend the children's book Gavi and Shalomit the Shabbat Bear/ Get Ready for Shabbat by Evita Tierman. It tells how everyone including the teddy bear thinks it's important to get ready for Shabbat. It is very cute and I think it would appeal to youngsters from Nursery to fourth grade. It's written in simple language and has beautiful pictures. I know that many parents would like to have a book like this for their children.
