All Saint's Day
Print and cut out the pictures of the saints' symbols, and place (or outright hide!) in various areas of your home or classroom. This is a great opportunity to talk about why each of these symbols might be associated with its particular saint.
Alternately, if you have the time and the ability, you can use actual objects in place of the 2-D images (e.g. a real candle, stuffed lamb, a carpenter's tool, etc.)
