Topics for Displays- these don't necessarily fit into any units of study K-5 but highlight topics of interests to students; likely that Libraries in general have at least a few books that would fit into each category in order to make a nice display; lend themselves to displays.
Anne of Green Gables (find props on your holiday visit to PEI)
Ones that I wish we had more books of to make displays:
Horse picture/story books.
Jesus growing up.
