Seattle Math Myth Buster Charlie Mas writes

As usual Charlie Mas puts together a very fine piece.

Does the SPS have a definition of curriculum and if so do they use it? Charlie again points out how incredibly inconsistent the SPS appears to be.

How can the SPS tell us much when there is no internal consistency?

I really like Charlie's writing.
