I love the expansion into Reading with the Beta reading courses. I understand this is still a growing project and will most likely change. I do think it would still be more helpful to educators to some level of a curriculum map that we could quickly scan and decide which content to use at different points in our school year.
I imagine/hope that the folks at Khan developing this curriculum have some form of internal map to help keep things organized. Could that be adapted to a viewable document (Google, Word, etc...) that is shared out and would always have the latest updated version?
