If you are looking for some inspiration and/or entertainment for you or your students, check out the Vi Hart’s Blog. Vi is a “recreational mathemusician” (her words, not mine) who creates interesting videos about mathematics and music. They are highly entertaining – perfect for for high school students, but also teach real mathematics and critical thinking. My favorite is the Binary Hand Dance:

which is a fun and catchy way to demonstrate binary numbers. Just watch it, then tell me you weren’t practicing on your own when no one was looking ;-).
