Give students a sum of fake money. Students will use the fake money to "buy" a scripture. The teacher auctions off different significant verses in a block of scriptures that students can search for principles and applications. You might even attach different candy to different verses -- the "better" the verse (or, the more things to describe in the verse) the better/more candy there is so it is "worth" more. After everyone has won a scripture, students will find the "treasure" in the verse(s) they have to show the worth of what they purchased.
