Mathematics Common Core Standards

  • Formative Principles of the Common Core Standards
  • Against "Answer-getting"
  • Planning Chapters, Not Lessons

These define the content of a student's mathematical character.

- Phil Daro

Phil Daro talks about the principles that he and the other Common Core Standards authors used in forming the new standards, their intention and their vision. Daro speaks to the potential that these standards have to make change in the US national education system.


Correct answers are essential... but they're part of the process, they're not the product. The product is the math the kids walk away with in their heads...

- Phil Daro

Phil Daro goes into detail on the problems of "Answer-getting," one the practices that the new Common Core Standards intend to greatly reduce.


There's a lot of value to getting it just about right, and a lot of cost to getting it wrong, and what we discovered is that mathematics does not break down into lesson-sized pieces.

- Phil Daro

Phil Daro describes how lesson-sized pieces do not serve mathematics well, and that chapters provide a much better grain size for the material.
