I know there's a math lesson a mathematician or topologist could explain, but for now I'm just stoked to share that a game the girls play on paper actually IS mathematical. As they watched, they'd point out with raised eyebrows and wide eyes, "Hey! I do that!"
There are loads more at Vi Hart's blog. Enjoy!
AMAZING! I want to stick this in my pocket until my kids are old enough for it. Thanks so much for sharing!
