Important Ideas about Standards

4: modeling with mathematics 

- model real wold applications to mathematics 

- choosing and using appropriate math methods and skills for the problem at hand 

- visually representing mathematic questions, reasonings and solutions 

- engaging students with a variety of different of modeling problems 

8: look for and express regularity in repeated reasoning

- patterns in mathematics help to develop students' reasoning 

- helping students to find efficient methods to problem solving 

- developing regularity in calculations can help students recognize irregularities due to mistakes.
