One of my best friends lives in Pennsylvania. They have a lot of those Scottish/Celtic or medieval festivals in the summer that they go to.
I was looking at her pictures on facebook and my kiddo was fascinated by the costumes. My friend had even upload a small video clip of one of the bands playing music complete with bagpipes.
My little guy was so interested that we started looking stuff up. I turned it into a teachable moment.
Do you do things like that? Just when something random sparks an interest and you immediately capitalize on it to teach them something?
