Or you could make up a treasure hunt game with her, I.E let her do most of the thinking, But you explain how it works. Get her involved in placing the clues in different rooms. Once placed, you get the other kids to look around, and get involved. It can be about the bible and make it fun. and when they find the treasure, make sure there's enough for all.
or you could place wildcards in there rooms, when they find them, they bring to you, and you then explain the wildcards through the bible. But don't do it everyday. just now and then. Example: the wildcard could say the word Love. you then get the bible out and point to a few verses that contain that word. you can extend it but finding pics to colour in that relates to the wildcard. and then make cakes to finish off.
