Mathematical Practices
* Make sense of problems and
persevere in solving them
* Reason abstractly and
quantitatively
* Construct viable arguments and
critique the reasoning of others
* Model with mathematics
* Use appropriate tools
strategically
* Attend to precision
* Look for and make use of
structure
* Look for and express regularity
in repeated reasoning
