The Exponential Curve  Dan Greene
http://exponentialcurve.blogspot.com/
A blog by Dan Greene, a math teacher at Downtown College Prep charter high school (San Jose, California), where the students "... are primarily Latino, are far below grade level in their math and reading skills, and will be the first in their families to go to college. We refer to our students as being on an exponential learning curve: the average level in math of our incoming freshmen is 5th grade, and we need to get them to a 12th grade level in 4 short years."
Greene describes the purpose of his blog, which dates back to June, 2006, as helping "generate and share ideas for teaching high school math concepts to students whose skills are below grade level."
