Meet self-made millionaire ... teacher?

CNN features a Georgia elementary teacher who has made over a million dollars on Teachers Pay Teachers, an online marketplace where teachers can put up their creations for sale. TPT has caused a stir lately amongst math teachers on Twitter, as those who've enjoyed the free sharing of ideas are resisting the more entrepreneurial perspectives shared by TPT users. Not surprisingly, I tend to side with the "free sharing" camp, but I think there's a larger story playing out: if researchers and curriculum experts want to keep their high-quality curriculum materials in teachers' classrooms, they'll need to rethink and adapt their marketing strategies.
