I recently attended the M4 Conference in Kansas City, where math leaders from Kansas, Missouri, Nebraska, and Iowa met to discuss the Common Core Standards for Mathematics. I was privileged to hear from Matt Larson the keynote speaker from Lincoln, Nebraska. After humerously acknowledging that his state was one of the four who had, as of yet, not adopted the common core standards, Larson got right to work convincing us that the Common Core State Standards may be our last opportunity to get math education right!
