Tom Vander Ark: Back of the Envelope Calculation on U.S. Adoption rate of Blended Learning

Here's my thinking.
Home schooling will double to more than 3 million students.
Virtual schools (mostly charter) will see full time enrollments climb to 1.5 million.
With home education, that’s almost 5 million kids educated at home, or nearly 10 percent.
New blended schools, mostly charters, will serve more than 1 million kids.
A couple chains like Rocketship will serve a couple hundred thousand kids.
There's more to my pencil calculations, including a chart and a graph.
