In stories, kids are always making connections to their every day pop culture realities. They need to be encouraged when they suggest cute answers connected to their pop culture.
I remember last year for a while the kids in my middle school were totally into leprechauns. I asked them why. I got a hundred answers – because they have gold, they are little and green, they own a cereal, they have green top hats that make them a normal height, they have pointy ears, they have bad teeth, they have Irish accents, etc.
My point is that I’m not into leprechauns, and so it would be easy to miss the opportunity, but that if I can plummet into the strange fascination that my students have with them, and build them into stories in some way, chances are, it can only support the story.
