Every tech-savvy educator has heard it before - a colleague's plea for a great program or interactive website to use in a particular lesson. Often the requests are easily answered with a shouted-out URL; other times, not so much. That was the story for me, last week, as not one, but two colleagues asked me if I "knew any good math sites." Well, yes, I know quite a few, in fact I have an entire category devoted to the subject here on NCS-Tech, but I don't think they read my blog. Much. Or ever. :) It's not entirely their fault. They are busy people. Who has time to read blogs? :) They know I live and breathe this stuff, that I'm constantly finding and sharing great resources, hanging out on some street-corner in Twitterville like the knowledge junkie I am, waiting to score my next hit. So um, yeah. I know some good math sites! :) Then there's always... more.
